Merge Core main into german/hal-644-ar: Arabic on the Vue UI

Main moved the UI to Vue views and Pinia stores, so the Arabic changes to
the old DOM controllers now live in their views: the rail legend range
comes from formatScaleRange (keeping units a source supplies as given),
the voice timeout options are worded by Intl unit formatting in
VoiceControl, and the scene editor's JSON fields stay left to right in
SceneDialog. Main's CCTV status line, launch panel and calibration values
keep the Arabic isolates and Western-digit formatting.

isolate() and keepCodesWithValues() read the locale through getLocale(),
which follows the page's vue-i18n instance, and the Intl formatters take
intlLocale(getLocale()). A language switch now applies in place, and
applyDocumentLanguage sets <html dir> on every switch, so the page mirrors
without a reload.

The icon rails and their tips are placed with logical properties, so they
stay on the outer side of the mirrored stacks; Cyber's new stack offsets,
padding and edge lines are logical too, and rtl.css moves Cyber's right
stack to its new rail clearance. Main removed the Context mini radio, so its
right-to-left rules and test go.

The Arabic catalog gains main's new strings and drops the ones main no
longer uses; the other catalogs keep main's new keys and the branch's
landing labels.

+## Building UI
+
+New UX elements are Vue components whose state lives in a Pinia store, and so
+are existing ones when a change converts them:
+
+- **Views are Vue components.** Application views live in `src/ui/views/` and
+  the components they place in `src/ui/views/panels/`; a component that
+  belongs to one feature sits beside its owner (`src/ui/rail/`,
+  `src/ui/weather/`). A view renders what its store holds and forwards
+  clicks and input to the store; it holds no application logic.
+- **State lives in a Pinia store** in `src/ui/stores/`. The owner presents a
+  plain view object and publishes it to the store; the view renders it. User
+  actions return to the owner through handlers it connects to the store,
+  which replace an earlier owner's. Where several owners answer different
+  actions of one store, use `createOwners()` from `src/ui/stores/owners.js`:
+  `act(name, ...args)` calls the newest connected owner that handles `name`,
+  and the owner calls `detach(token)` when it stops.
+- **Portable owners stay framework-free.** An owner in a portable export
+  imports neither Vue nor Pinia: it takes a `publish` option or offers a
+  `subscribe…()`, and the application shell connects it to the store.
+  `npm run check:boundaries` enforces this.
+- **Reuse the kit first.** `src/ui/kit/` has one component per control:
+  `UiButton` (including pressed toggles and pressable chips), `UiSelect`,
+  `UiSlider`, `UiSegmented`, `UiChip` (a label, not a control), `UiBadge`,
+  `UiEmpty`, `UiIcon`, `UiTooltip`, `UiPanel` and `UiRail`. Use these before
+  writing a control. When the kit lacks something, extend a kit component or
+  add one that follows the kit's names, props, events and class names (see
+  [Component kit](docs/VUE-MIGRATION.md#component-kit)), rather than
+  building a one-off.
+- **No hand-written DOM binding.** Don't build elements or write text,
+  classes or attributes from a controller to show UI state; render it from
+  the store. New controls take input through the store rather than through
+  listeners the owner adds. To render outside the view's host (the body, the
+  globe container, or a slot another surface opens), use `<Teleport>` to
+  `body`, a fixed id or a container the owner publishes; don't move nodes by
+  hand. What stays imperative: classes on `<body>` and `<head>`, which sit
+  outside Vue (`cockpit-mode`, `ui-clean-view`); focus moves; positions a
+  layout pass measures in the same task that writes them; and surfaces an
+  owner paints or plays, such as the Cesium canvas, overlay canvases and live
+  video. A few existing surfaces keep listeners or bindings that
+  [docs/VUE-MIGRATION.md](docs/VUE-MIGRATION.md) records; keep those
+  contracts when you change them, and don't copy them into new UI.
+- **Text** goes through `t()` or `tn()` where the template renders it.
+  English kept in a constant or a store is marked with `msg()` and passed to
+  `t()` when it renders, since a `t()` at module load would fix the English.
+- **Test components, not markup strings.** Mount the component over
+  happy-dom with `@vue/test-utils` or `createApp` and assert what it renders
+  from its store (see `src/testSupport/vueDom.mjs`, `src/ui/kit/*.test.mjs`
+  and `src/ui/views/intelHudView.test.mjs`). Run one such file with
+  `node --import=./build/registerVue.js --test <file>`. Don't pass happy-dom
+  nodes to `assert.equal`/`deepEqual`; compare them with `assertSameNode()`
+  from `src/testSupport/domAssert.mjs`.
+
+[docs/VUE-MIGRATION.md](docs/VUE-MIGRATION.md) records how each surface moved
+and what stays imperative, and why.

 - **Kartverket ground heights for Statens vegvesen cameras.** The camera feed's points are 2D, so the loader asks Kartverket's keyless point-height API (`ws.geonorge.no/hoydedata/v1/punkt`, CC BY 4.0) for the terrain height at each camera. Requests carry 20 points: the API accepts 50, but above ~20 it answers the extra points from contour lines (`hoydekurver`, metres to ~20 m off) or not at all. Eight requests run at a time, about 36 for the whole country: a cold lookup took 6–13 s in testing (single requests 0.6–9.5 s). Answers are matched by the coordinates the API echoes and recorded only for points that request asked about. Over water the API returns the sea-floor depth (`dybdekurver` or `Havflate`), which is replaced by 0 m, the water surface; for the ~14 bridge cameras that is below the deck, but much closer than the sea floor or the flat prior. Heights are cached in memory by position for the life of the server, and points with no height (a few ferry quays and bridges, or a point a 200 answer leaves out) for 6 h, so the 15-minute catalog refresh only asks about new or moved cameras. The first failing request (a 408, 429 or 5xx, a network error, a request over 10 s, or an unreadable or oversized body) stops the lookup, with no retries, and no new lookup starts until the backoff ends (Retry-After when sent, else 30 min, longer than the refresh; bounded to 1 min–1 h). Any other 4xx marks that request's points as having no height and the lookup carries on. The whole lookup has a 30 s deadline; a lookup cut short by it resumes on the next refresh without a backoff. The lane waits at most 12 s, counted from the start of the loader, and only when more than 10% of the cameras have no answer yet; a few new cameras or expired misses are looked up in the background. A slower lookup keeps filling the cache, and the cameras it had not reached keep the flat prior until the next 15-minute refresh (about 190 of 865 on one slow first run). Only coordinates are sent, with the same User-Agent as the other CCTV requests. `CCTV_VEGVESEN_HEIGHTS=0` turns the lookup off. The Kartverket credit, with a note that heights over water are set to 0 m and heights are rounded to 0.1 m, is shown beside the Statens vegvesen entry in the Data attribution popover.
 - **NYC DOT Traffic Management Center cameras.** Off by default. NYC DOT's [developer data feeds page](https://www.nyc.gov/html/dot/html/about/datafeeds.shtml) asks developers who want the camera feed to contact `[email protected]` and sign a data-sharing agreement. This project does not hold one that covers downstream installations, so the pack loads only when an operator who holds their own agreement sets `CCTV_NYC_ENABLED=1`; with the flag unset, empty or any other value, the server makes no request to NYC DOT. The endpoint needs no key. The camera list is the public `webcams.nyctmc.org/api/cameras` catalog (~980 cameras across the five boroughs); frames are stills at `webcams.nyctmc.org/api/cameras/<uuid>/image`, synthesized from a validated UUID rather than taken from the payload, and only that host is registered. Cameras the feed reports as offline are dropped. The catalog publishes no camera facing, so headings use the shared id-hash fallback at low confidence and are corrected with the in-app calibration gizmo. Once enabled, the 250 cameras nearest the borough cores load; `CCTV_NYC_MAX_SOURCES` (8–400) changes the cap. Frames are fetched at request time and never stored or redistributed. NYC DOT asks every application that uses its data to carry its disclaimer; it is registered verbatim in the Data attribution popover.
 - **City of Toronto RESCU cameras.** Keyless. The camera list is the City's public `tmcearthcameras.json` on `opendata.toronto.ca` (dataset "Traffic Cameras", Transportation Services), served as JSONP and unwrapped with an anchored pattern. This is the municipal network the Ontario 511 pack does not carry: downtown arterials plus the Gardiner, DVP, Allen and Lake Shore. The list publishes no frame URL, so frame URLs are BUILT from the documented `CameraImages/loc####.jpg` convention and a strictly-digits camera number, pinning the frame proxy to the portal origin by construction; the list fetch refuses redirects and bounds the body it buffers. Frames are fetched at request time and never stored or redistributed. The dataset publishes no camera facing: the `D1`-`D4` fields are the directions of the *comparison* images (static reference stills captured in 2016 under a different path), not a bearing for the live pan-tilt-zoom frame, so headings use the shared id-hash fallback at low confidence and are corrected with the in-app calibration gizmo. A camera that is temporarily out of service still answers 200 with a byte-identical "Image Unavailable" placeholder rather than an error (about 6% of the network at any moment), so such a camera reads as healthy; the frame it shows is the agency's, not a synthesized one. The licence requires the attribution statement above. Disable with `CCTV_TORONTO_ENABLED=0`.
+- **Autostrada del Brennero (A22) webcams.** Keyless. The camera list is one request to the Open Data Hub tourism API (`tourism.api.opendatahub.com/v1/WebcamInfo?source=a22`), run by NOI Techpark in South Tyrol, which republishes Autobrennero's own list of 13 motorway webcams with coordinates and kilometre markers. Frames are the operator's stills on `www.autobrennero.it/WebCamImg/km<N>.jpg`, refreshed about once a minute, and only the exact image for each camera's kilometre is registered. The feed names no bearing, so headings use the id-hash fallback at low confidence. The road climbs from about 20 m in the Po valley to about 1,370 m at the Brenner Pass, so each camera's ground elevation comes from a per-kilometre table sampled from the Copernicus GLO-90 DEM (via Open-Meteo's elevation API); a camera not in the table uses a 200 m prior. The Open Data Hub tags every record CC0 (`ClosedData: false`, Autobrennero as licence holder), but that tag is the aggregator's metadata and Autobrennero publishes no terms of its own for the images, so they are credited to the operator as a courtesy and are not redistributed. Frames are fetched at request time and never stored. Disable with `CCTV_A22_ENABLED=0`.
 - **Camera frame content.** Public camera frames can contain people, vehicles and license plates, and the camera layer does nothing with them beyond putting them on the map. A successful upstream response is relayed as the provider served it: nothing in the camera pipeline blurs, redacts, enhances or restores it, and nothing there runs face, plate or object detection or otherwise recognises or classifies what is in the picture. (The ALPR layer described below maps where plate-reader cameras are, from locations contributors tagged in OpenStreetMap; it reads nothing from any camera frame.) When an upstream has no frame for a camera, what you see instead is a Google Street View still or the app's own placeholder card; the panel's source badge names which of them you are looking at, and a refresh that fails after a frame has arrived leaves the last good picture on screen rather than replacing it. The browser resamples each frame for display: onto a fixed 1920x1080 surface for the camera's projection plane in the scene, and onto a 192x108 canvas for the small ambient card. That scaling is the only change made to the picture, and the only pixels the camera layer reads back are a 64x36 downscale hashed to tell whether the picture has changed. Live streams are piped through; the still path reads the image into memory to pass it on — TxDOT wraps its JPEG in a JSON envelope, which is decoded there — and no frame is written to disk (the disk cache, `.gev-cache/`, holds feed JSON for other layers and never camera imagery). Outside that pipeline, the voice assistant is the one feature that sends imagery anywhere: when it answers a question about what is in view it may attach a downscaled screenshot of the rendered scene — including any camera plane on screen — to the request it sends to the voice model. Frames are fetched only from server-registered camera URLs — a client cannot hand the proxy a URL (see [SECURITY.md](SECURITY.md)). What the app does stays inside the line README draws: no named-person search, no face recognition, no tracking individuals.
 - **Transit (GTFS-Realtime).** The proxy requests only registered operator feeds, validates redirects, bounds responses, and uses conditional requests, short snapshot caching and failure backoff. All sixteen registered regions are live-enabled; each can be disabled independently. Vehicles use delayed playback between reports, with report age and waiting states shown separately. Session-local selected trails are available for every feed. MBTA additionally retains up to 15 minutes of recently observed positions in the running proxy, so available history can survive a browser reload; server restart clears it. History reads never fetch upstream, and other feeds have no proxy retention. Nothing is archived to disk or collected in the background. Operator text credits are included as a courtesy and do not imply endorsement. Heights are aligned to work with Google 3D tiles; subway markers are shown at street level because these feeds do not supply depth. The TTC feed is BusTime, the surface system: it carries buses and streetcars and no subway at all. About four in ten of its vehicles report no route at all (unassigned or deadheading), and those are shown with the feed default rather than a route-established mode. It sends no ETag or Last-Modified, so its conditional requests fall through to the ordinary snapshot cache. Three Golden Horseshoe neighbours run alongside it — MiWay, Hamilton HSR and Durham Region Transit — each bus-only and each polled only near its own region. Durham Region Transit publishes no bearing on any vehicle, so those sprites take their heading from observed movement like any other feed that omits it. Guelph, Kingston and Barrie extend the same pattern eastward and north. Hamilton, Guelph, Burlington and YRT publish route ids that are not the number on the vehicle, so those entries carry a route-name table taken from each operator’s own published GTFS; any id missing from a table renders unchanged rather than blank. A label is never invented: YRT runs a route `9101` that appears nowhere in its published routes, so it stays as the feed sends it. Burlington’s is the one that cannot be shortcut: `351` is route 1 while `3510` is route 10, so the table is a real join rather than a trimmed prefix. GO Transit / Metrolinx is deliberately absent: its REALTIME feed requires an API key issued by manual review, which the keyless admission rule excludes (its static schedule download is keyless, but carries no vehicle positions). Barrie and YRT/Viva each invite acceptance of their licence through a form, and each licence also states that using the data is itself acceptance; this deployment relies on that clause, which is recorded in both entries. Grand River Transit in Waterloo is absent for a different reason: it answers, but its feed header was months stale and it publishes no per-vehicle timestamps, so it would render vehicles that look live and are not. Ottawa’s OC Transpo falls to the same keyless admission rule as GO Transit — its realtime feed requires an API key. London Transit and Thunder Bay Transit publish vehicle positions over plain HTTP with no HTTPS endpoint available. Every other Ontario system — Brampton, Oakville, Niagara, Milton, Windsor, Greater Sudbury, UP Express and a dozen smaller operators — publishes static GTFS schedules only, with no realtime vehicle positions to register. Between the nine included and these exclusions, every Ontario realtime vehicle-position feed catalogued in the Mobility Database is accounted for.
 - **Radio Browser.** `/api/radio/stations` discovers official API mirrors, makes bounded and coalesced healthy/geolocated HTTPS-station queries, caches the normalized public-domain directory for 45 minutes, and may serve the last good catalog for up to seven days during an outage. Refreshes must meet minimum accepted-query and station coverage before replacing a warm catalog; schema-valid responses whose rows all fail the product's health policy do not count as successful queries. A usable partial cold catalog is explicitly `DEGRADED`, and non-array or empty successful payloads are rejected atomically. Individual structurally malformed rows are skipped rather than failing the whole query; the response carries their bounded `rejectedStationCount` (at most 10,000), which the client adds to its own rejected rows and reports as degraded coverage without discarding the accepted generation. Every directory and click-count request rejects redirects, validates all resolved addresses as globally routable (including reserved/documentation IPv4 and special/non-global IPv6 exclusions), and pins the TLS connection to a validated address. Only MP3/AAC non-HLS directory rows with public HTTPS stream targets are returned; favicons are intentionally omitted. Pressing play connects one browser audio element directly to the selected broadcaster and calls the directory's click counter through known-ID-only `POST /api/radio/click/:uuid`. GEV never proxies, caches, records, bundles, or redistributes audio. Radio Browser supplies station-level tags, not dependable current-song or upcoming-program metadata, so Radio filtering never claims either. Direct playback exposes the listener's IP address to the broadcaster, whose own stream terms apply.

 - **Server-side credentials.** Every API that touches a private key (OpenAI, AISStream, OpenSky OAuth, camera frames) is brokered through a hardened server-side proxy with SSRF protection, response caps, and sanitized errors.

+- The language picker switches language in place instead of reloading the

+  through `onLocaleChange` (`src/i18n/index.js`), and `<html lang>`/`dir` and
+  the page's `data-i18n` markup follow. `persistLocale` replaces
+  `persistLocaleAndReload`, and `registerUnsavedWork` and the switch's
+  unsaved-work prompt are removed, since a switch no longer loses anything
+  (samehkhamis, #1499).
+
+- A map source's `unavailableReason` may be a function, read when the reason
+  is shown so it follows the locale; the sources from `createDefaultMapSources`
+  (`./maps/defaults`) give functions. `MapSourceController` reads either form
+  (samehkhamis, #1499).
+
+- The application views translate their text with `t()` as they render,
+  so it follows the active locale; they no longer carry `data-i18n*`
+  attributes, and `npm run i18n` rejects those in a Vue template. The boot
+  pass (`applyDocumentTranslations`) still translates static page markup
+  such as the loading screen and a host's own markup (samehkhamis, #1499).
+
+- The page's locale lives in a vue-i18n instance installed in every
+  application view, and `t()`, `tn()` and the Intl formatters read it from
+  there, so a view that translates while rendering renders again when the
+  locale changes. `bindLocale` (`src/i18n/index.js`) keeps the locale in a
+  given ref; Core's Vite config builds vue-i18n without its message
+  compiler. Catalogs, messages and call sites are unchanged
+  (samehkhamis, #1499).
+
+- Cockpit's Display popover shows the Display panel's own HUD, Detection,
+  Parameters and 3D groups through Vue teleports: `CockpitDisplayPortal`
+  publishes the popover's slots (`publish`, with `afterRender` to lay out once
+  they have moved) instead of moving the groups itself (samehkhamis, #1499).
+
+- The Cockpit utility strip's measured layout renders from the `gev-cockpit`
+  store: the layout pass publishes `utilityLayout` (the HUD's
+  `--cockpit-utility-*` lengths, `primaryOnly` and `hideCollapsed`), and a host
+  constructing `CockpitController` passes `publish.utilityLayout` beside its
+  other publishers (samehkhamis, #1499).
+
+- The Cockpit Contact and briefing cards' collapse renders from the
+  `gev-cockpit` store: the controller publishes `contextCollapsed` and
+  `signalCollapsed` in its presence, and each card's `data-collapsed` and its
+  toggle's state, words and icon follow it (samehkhamis, #1499).
+
+- The panels' own state classes (`collapsed`, `dock-pinned`, `dock-pinned-top`,
+  `layout-auto-collapsed`, `accordion-collapsed`) render from the
+  `gev-panel-chrome` store: the shell, the rails and the accordion present each
+  panel's state there instead of writing its classes. `layoutLeftPanelRail` and
+  `layoutRightPanelRail` (`./ui/layout`) now call
+  `onCollapse(panel, {collapsed, auto})` and leave drawing it to the host.
+  Without a shell to own the panels, the voice tools' `set_panel_open` now
+  reports that there is no panel to open instead of writing its classes
+  (samehkhamis, #1499).
+
+- The shell's panel chrome no longer writes the panels' collapse buttons, the
+  dock tray toggles' names or the dock pins' pressed state: it presents each
+  panel's open and pinned state to the `gev-panel-chrome` store, and the
+  buttons, now views, call it there. `bindPanelDisclosure` (`./ui/panels`) binds
+  only a panel's Escape; it no longer takes `buttons` or `onChange`. `UiButton`
+  joins the component kit (samehkhamis, #1499).
+
+- `SceneControls` (`./ui/scenes`) no longer takes `elements` or writes the Scene
+  panel's buttons, status, progress or runtime chip: it presents them to the
+  `gev-scenes` store and the panel's buttons call its actions there.
+  `sceneElements`, `presentSceneButtons`, `presentSceneProgress` and
+  `presentSceneRuntime` give way to `sceneButtonsDisabled` and `scenePercent`.
+  It no longer stands down when the page has no Scene panel: ESC still stops a
+  playing scene and the runtime chip still shows (samehkhamis, #1499).
+
+- `initFirstRunExperience` (via `./application/chrome`) no longer writes the
+  launcher's classes, attributes or text, or removes the card: it presents them
+  to the welcome view's `gev-first-run` store (its new `store` option) and
+  connects the controls the view's buttons call (samehkhamis, #1499).
+
+- `IntelHUD` (`./ui/hud`) no longer builds or writes `#intel-hud`: it hands its
+  readouts, visibility, layout variant and style colors to its `publish` option,
+  and Core's `intel-hud` view renders them. A page places that view with
+  `<div class="gev-view" data-gev-view="intel-hud">` instead of a bare
+  `#intel-hud` element. `./layers/vessels` shows the selected vessel's HUD
+  readout through `services.readouts.presentSelectedVessel()` instead of writing

+  follows (samehkhamis, #1499).
+
+- `LocationControls` (`./ui/location`) no longer builds the city and landmark
+  pills or writes the mini status: it presents the tray, including the search
+  error (`setSearchError()`), and hands it to its `publish` option, and Core's
+  dock renders it and calls `chooseCity()` and `choosePoi()`. Its `elements` are
+  now only `search`: `resetButtons` and `searchToggle` are gone, and the reset
+  buttons and the search toggle call its new `reset()` and `toggleSearch()`. It

+  `setSearching` option in place of writing the field's class, and
+  `NavigationController` a `settleSearch` option in place of `searchInput`.
+  `createOrbitIndicator()` is replaced by `showOrbit(active)`, which adds the
+  ORBIT indicator to the presented tray as `orbit: { active }` (null until
+  offered) (samehkhamis, #1499).
+
+- `createMapSourceControls()` (`./ui/maps`) no longer renders the map source
+  chips into a `container` or writes a `statusElement`: it presents the chip row
+  and status badge and hands them to its `publish` option, and Core's dock
+  renders them and calls `select()`. `renderMapStackChips`, `syncMapStackChips`
+  and `MAP_STACK_CHIP_CLASS` are removed (samehkhamis, #1499).
+
+- `./layers/launches` no longer writes the Space Missions roster or the selected
+  mission panel into `#space-mission-panel-host`: the layer publishes both
+  through `subscribePanel(listener)` and Core's Space Missions views render
+  them, calling the layer's panel commands (`selectMissionAt`,
+  `selectPreviousMission`, `selectNextMission`, `deselectMission`,
+  `focusSelectedLaunchSite`, `startSelectedReplay`, `toggleReplayPause`,
+  `cancelReplay`, `setReplaySpeed` and the `roster*` preview inputs). The
+  `bindMissionRosterItemKeyboardPreview`, `captureMissionRosterFocus` and
+  `restoreMissionRosterFocus` helpers are gone; the roster keeps focus itself
+  (samehkhamis, #1499).
+
+- `./layers/awareness` no longer writes the Contacts panel into
+  `#military-awareness-panel`: the layer publishes a plain panel view through
+  `subscribePanel(listener)` and Core's Contacts view renders it, calling the
+  layer's `navigatePrevious`, `focusCurrent`, `navigateNext` and `focusTarget`.
+  The `awarenessPanelControlKey`, `captureAwarenessPanelFocus` and
+  `restoreAwarenessPanelFocus` helpers are gone; the view keeps focus itself
+  (samehkhamis, #1499).
+
+- `./ui/cctv` and `./ui/radio` import Vue and Pinia: their controllers publish
+  the panel's state to a store that the CCTV and Radio views render, instead of
+  writing the panel's markup themselves (samehkhamis, #1499).
+
+- `./ui/display`'s `bindDisplayControls` is gone: the Display panel's controls
+  and the dock's style buttons call their owner through the display store's
+  `connect`/`act`, and its allocation and 3D model choices are the kit's
+  `UiSegmented`. `initDrawTool` takes `connect(actions)`, which returns their
+  disconnect, and no longer listens on the Draw controls; its view publishes
+  `color` and `label` too, and the shape choice is a `UiSegmented`.
+  `initGeoFileImport` takes `connect(actions)` the same way and no longer
+  listens on the Import button, picker or list, nor restores focus itself: the
+  `GeoImport` view does both, and its `publish` need not settle once the list
+  renders. Street Level's fit and panorama filters and Recent Imagery's mode are
+  `UiSegmented` too: the Street Level store's owner answers `setPano` and
+  `setRenderMode`, and `RecentImageryReadout` takes `onSetMode`. The Radio
+  panel's and Cockpit's internet radio controls and the tuner slider's events
+  call `RadioControls`, and the local RTL-SDR card's controls
+  `LocalSdrControls`, through the radio store's new `connect`/`act`; the card
+  labels its gain options itself. `act` returns what the answering action
+  returned. The Display, Radio, RTL-SDR, Cockpit, mission replay, style
+  parameter, rail card, observation timeline, imagery opacity, Street Level date
+  and Bhote Koshi sliders are the kit's `UiSlider`, a native range input that
+  emits numbers, and the pressed toggles are the kit's `UiButton`, which gains
+  `pressedClass`; so are the rail card chips, map source chips and location
+  pills (which now report `aria-pressed`), and the voice card's chips are the
+  kit's new `UiChip`. The selects are the kit's new `UiSelect`, the status
+  badges its new `UiBadge` and the one-line empty states its new `UiEmpty`. The
+  top-center clear, share, tilt, north-up and reset buttons, and the cockpit's
+  reset, call the shell through the new globe actions store, which also carries
+  the camera's tilt and compass heading. The recording safe frame renders what
+  `RecordingControls` publishes to the new recording store. `syncScopeControls`
+  (`./ui/display`), `shouldHideCollapsedRightPanels` (`./ui/layout`),
+  `bindClearLayersControl` (`./ui/layers`) and `createStyleParameters`
+  (`./ui/input`; the Display panel renders the style parameters VisualSettings
+  publishes to the display store) are deprecated: the Display view, the rail and
+  the globe actions view now own what they did. `./ui/input` imports Vue
+  (samehkhamis, #1499).
+
+- `./scenes` presents the scene sharing dialogs and the EDIT DETAILS / SHARE
+  SCENE bar through a store that the scene panels view renders, so a page that
+  omits `layer-panels` shows neither (samehkhamis, #1499).
+
+- `./voice/control`'s `createVoiceControl({ panel })` returns the voice
+  control's presenter instead of element handles: owners write it by part
+  (`update('detail', { text })`) and listen with `on('button', fn)`, and the
+  command dock renders it from a store. `createVoiceCommands`' `createControl`
+  and `VoiceCardControls` (`{ ui }` instead of `{ root }`) take the same
+  presenter; the `reset` option is gone, since a newer control replaces the
+  previous one (samehkhamis, #1499).
+
+- Pages place each view with a `<div class="gev-view" data-gev-view="NAME">`
+  host and write their own loading screen; the `build/html` template expansion
+  and its `gev:template` markers are gone. `createApplication` takes `omitViews`
+  (for example `['provider-settings']`) for views an application leaves out
+  (samehkhamis, #1499).
+
+- The page's panels, dock, cockpit and dialogs are Vue views with the same
+  markup as before. Hosts that do not initialize Core's locale pass
+  `localePicker: false` to `createApplicationControls` to drop the language
+  picker, and Node tests that import application modules register the component
+  loader with `--import=<core>/build/register-vue` (samehkhamis, #1499).
+
+- The Data, Authoring, Weather, Recent Imagery, Context, CCTV, Street Level and
+  Radio panels are one component, `UiPanel` (`src/ui/kit/`), with the same
+  markup plus the kit's `ui-panel` classes, their titles translated by `t()`
+  rather than `data-i18n`; `RailPanel` binds it to the panel chrome store.
+  `PanelCollapseButton` drops its `initial` and `initialTitle` props and takes
+  `startCollapsed`, so before startup presents a panel its button already shows
+  that state's glyph, words and `aria-expanded` (samehkhamis, #1499).
+
+- The Authoring, shot list and CCTV buttons and Street Level's nearest button
+  are the kit's `UiButton` (danger buttons in the `alert` tone, primary ones the
+  `primary` variant), keeping their classes; the CCTV on/off, coverage,
+  auto-hop, projection and adjust toggles now say their state with
+  `aria-pressed` (samehkhamis, #1499).
+
+- Each desktop sidebar has an icon rail that lists every panel on that side and
+  opens one with a click. One panel is open per side in every HUD layout, so the
+  collapsed panel headers no longer take up the sidebars. Phones keep the bottom
+  tab bar. The rail is the first view built with Vue and Pinia, which now ship

+## Panel rails
+
+On desktop each side stack has a floating icon rail (`src/ui/panelNavigation.js`,
+rendered by the Vue `PanelRailView` and the kit's `UiRail`) in the screen-edge
+gutter beside it. The rail lists every panel the side currently offers, in stack
+order: Data Layers and Authoring on the left; Display, CCTV, Weather and Recent
+Imagery (while shown), Street Level and Context on the right. Selecting an item
+opens its panel through `setPanelCollapsed(id, false, {explicit: true})`;
+selecting the open panel's item closes it. The item of the open panel is
+pressed (`aria-pressed`), and its tooltip is suppressed while the panel is open.
+
+One panel is open per desktop side, in every HUD layout. Opening a side panel
+by any route (rail, header, keyboard, voice) collapses its peers; restored or
+shared state that opens several is normalized by the layout pass, which keeps
+the most recently opened panel, then the one holding keyboard focus, then the
+first, and marks the others `accordion-collapsed` (presentation only, so share
+links still report the saved preference). Collapsed panels are hidden
+(`layout-exclusive`) because the rail lists them. The rail lives inside its
+stack, so it hides with it in Cockpit (where Authoring's item is also hidden),
+recording and clean view. The panel store (`src/ui/stores/panels.js`) mirrors
+each side's panels from the DOM; `PanelChrome` remains the disclosure owner.

 - The expanded `CONTEXT` view offers mutually exclusive `CONTACTS` and `SPACE MISSIONS` modes. Selecting `CONTACTS` enables the context-owned Flights, Military Flights, AIS Vessels, and Mapped Installations dependencies only when they are not already user-enabled; selecting `SPACE MISSIONS` enables the recent-launch layer and its Satellite dependency. `CONTACTS` cycles the nearest supported contact of whatever type is selected. Satellites are deliberately excluded from those Awareness cohorts and keep their own tracking UX. Selecting the active mode again returns to the neutral chooser and releases only mode-owned dependencies.
 - If a civilian or military aircraft is already tracked when `CONTACTS` becomes operational, that source-owned track is adopted as the Context subject before nearest-contact autofocus. Context rechecks the tracker after its dependencies settle, so a newer selection wins, while an explicit clear during activation prevents fallback from silently selecting a replacement. Cockpit entry remains unavailable until that Context transaction has settled, so its camera takeover cannot clear Cesium tracking before adoption. Adoption does not recreate tracking or transfer camera ownership; it initializes the normal 250 km ring, history, proximity results, and Cockpit Previous/Next state for the original aircraft.
 - `SEARCH NEARBY SITES` retains the bounded OSM results and makes one user-initiated, view-biased Google Maps Places text search for “military installation.” Google results are source-stamped, deduplicated against OSM by rounded location/name, and remain mapped context rather than operational claims. If Places is unavailable or the API is not enabled for the supplied key, OSM context remains available. A view across the antimeridian is searched around its own centre, with a radius from its real width.
+- The Context header holds only its title and collapse control. It no longer carries a Radio shortcut or a compact Radio player: Radio is the `RADIO` section inside the panel, with its own disclosure and the single `ENABLE` power control. Cockpit keeps its own compact Radio utility.
+- Context is set for reading in every theme: mode, standby and action labels are 10 px, and the panel draws no glow halo. Outside Cyber, the two modes form one segmented control, the standby guidance is plain left-aligned text rather than a dashed placeholder, and the panel's section titles share the side panels' dock-label colour. Cyber keeps its separately framed mode buttons, its red panel titles, and in layout-focus a framed, centred standby card over its radar art.
 - The expanded desktop header omits the redundant `ON` label; the active mode button carries state. Expanded Contact results also omit the duplicate `GLOBAL CONTEXT` / `CONTEXT ONLY` status row and begin with the selected subject and its 250 km scope. Global Context does not fabricate a selected-entity model preview: the provisional hand-authored aircraft wireframe was removed because it was not geometry extracted from the selected entity's actual asset.
 - Dependency ownership is reversible: disabling Global Context releases only dependencies it enabled, while user-enabled layers remain on. This also removes the Military-layer suppression handoff when Global Context owned Military, allowing an already-enabled civilian Flights layer to resume its normal mixed rendering. If OpenSky is unavailable and has no last-good cache, Flights requests a capped 250 nm adsb.lol point snapshot around the current view anchor and labels that provenance explicitly; it never relabels military-feed rows as civilian data. If both inputs fail, Flights remains `UNKNOWN`.
 - Space Missions is replay-isolated: Rocket Launches and Satellites are the only Data Layers permitted while the mode is active. Direct UI and voice entry capture the same pre-entry snapshot; internal dependency and restoration enables do not create a user-owned Context session. Entry waits for incompatible layers to shut down, direct incompatible enables are blocked before lifecycle work, and the entry gate remains active through the complete Rocket Launches enable. A newer same-target ON request takes ownership of the pending entry without releasing its isolation snapshot, including when it arrives while the prior request is awaiting the adoption guard. A caller abort, resource cancellation, newer OFF, or layer teardown waits for exact manager settlement and restores that snapshot without resurrecting Rocket Launches. If an abort lands after only part of a restore settles, Context completes the same exact target without the stale caller signal and then replays newer explicit layer intent. Dedicated Voice Context cancellation reports a stable cancelled result plus the current Context state; generic layer visibility additionally exposes manager phase, reason, successor, and lifecycle details. Once an exact voice visibility intent commits, a newer voice turn cannot relabel it as cancelled while Context settlement completes; pre-commit aborts remain cancellable and final lifecycle mismatches remain failures. Clear Selected Layers reserves its complete captured OFF set before sequential teardown; a newer absolute request of any origin supersedes only its layer reservation and remains authoritative. A rejected layer teardown retains the truthful enabled state, rolls already-stopped siblings back to the captured pre-entry set, and aborts replay; rapid exit/re-entry serializes the full Satellite enabled-state and parameter restore before a new snapshot is taken. Contacts remains additive and restores user-enabled layers normally.

 ### Manual Whiteboard Drawing (September 2026)
 
 - DISPLAY ▸ **Draw** turns the globe into a whiteboard drawn by hand. Pick a shape (Area, Line, Pin), click the vertices on the real world, type an optional label and pick a colour, and finish. **Keyboard contract, live only while Draw is on and never while you are typing in another field:** Enter finishes the shape (as does a double-click, and the two cannot both submit it — the session is replaced before the annotate call is awaited); Backspace removes the last vertex; Esc cancels the shape in progress, and a second Esc — Esc on an empty session — leaves draw mode. Typing in the label field keeps Backspace; Enter there also finishes. **Clear** wipes the board (the shape in progress and every placed mark), so removing marks does not require the console or the microphone.
-- Runtime entry: `createApplicationTools` (`src/app/tools.js`, behind the `src/standalone/tools.js` shim) calls `initDrawTool({ viewer, annotations })` after `initAnnotations` and defers its `destroy()`, so disposing the shell returns every DOM listener, the Cesium handler, the preview data source, the borrowed click actions and the `window.__gevDrawTool` handle. Its markup is a DISPLAY-rail component template (`src/ui/templates/display-controls.html`), assembled into `index.html` at build time. That handle (`setActive`, `setShape`, `addVertex(lon, lat)`, `finish`, `cancel`, `clearAll`, `diagnostics`) is the no-mouse test seam.

Its markup is in the DISPLAY-rail view (`src/ui/views/DisplayControlsView.vue`), rendered into its `index.html` host before the page is wired. That handle (`setActive`, `setShape`, `addVertex(lon, lat)`, `finish`, `cancel`, `clearAll`, `diagnostics`) is the no-mouse test seam.
 - Contract: a finished shape is submitted through the SAME `annotationEngine.annotate()` the voice agent uses, with geometry supplied and `manual: true` (`type: area` + `ring`, `type: route` + `path`, `type: pin` + coordinates). `resolveSpec` short-circuits manual specs (`resolveManualSpec`) so no geocoder, Places or Overpass call is made. A drawn area is a real (not synthesized) outline and drapes solid; a drawn line is a `route` with `mode: 'manual'`, labelled with its length and never a travel time; a pin is a point. Drawn marks therefore render with the whiteboard look, persist, de-dup, appear in `.list()`, and clear with `clear_annotations` / `.clear()`.
 - **A vertex is a lon/lat, and the mark is DRAPED.** Clicks are picked through `pickWorldFromScreen` — one of two scene helpers the annotation resolver factory (`src/annotations/resolver.js`) exposes alongside `sampleGroundHeight`, so the app has ONE depth-aware pick cascade rather than a second written beside it — which returns the height the pick landed on as well as the coordinate, so the live preview hangs on the roof or hillside under the pointer instead of sinking to sea level. The world renderer draws areas and routes with `clampToGround`, so the height is dropped at finish in one place (`finishSpec`) rather than being carried downstream and discarded silently: what you get is the outline you drew, lying on the surface beneath it.
 - **Draped marks classify onto `ClassificationType.BOTH`** — terrain AND 3D tiles — not onto 3D tiles alone. With only `CESIUM_3D_TILE`, every area fill, area outline, route and arrow rendered to nothing on a keyless boot, where Cesium's own globe carries Esri/OSM imagery and there are no tiles to classify against; the labels appeared and the geometry did not. That hit spoken annotations exactly as hard as hand-drawn ones. `scripts/qa-draw-tool.mjs` counts the mark's own colour in the rendered frame before and after a shape is finished, on a keyed AND a keyless server, so "the board says there is a mark" can no longer pass for "the mark is on screen".

 - Drawn-line distance labels select metres or kilometres after rounding to the nearest metre, so a 999.5-metre line displays as `1.0 km` rather than `1000 m`.
 - **Measurements and centres are computed on unwrapped longitudes** (`unwrapLongitudes` / `wrapLongitude` in `drawMode.js`, used by `ringAreaM2`, `ringCentroid` and the engine's manual-area anchor). A ~50,000 m² rectangle straddling the antimeridian reads its 0.002° width as 359.998° under raw arithmetic: it measured thousands of square kilometres and anchored on the Greenwich meridian, half a world from the shape. Path length was already safe — haversine is periodic in the longitude delta — and a test pins that so a "fix" cannot break it.
 - **Bounds.** One shape holds at most `MAX_VERTICES` = 512 points; two clicks within 0.5 m are one vertex (that is what makes a double-click finish without leaving a stray point); a vertex that is not a finite on-globe coordinate is refused. A shape that encloses nothing is refused rather than placed: three collinear points are not an area and a line under a metre long is not a line, and the hint says which.
+- Drawn-area measures round before choosing m², ha or km², so 9,999.6 m² displays as `1.0 ha`, not `10000 m²`, and 999,960 m² as `1.00 km²`, not `100.0 ha`.
 - Pointer ownership: while a session is open the tool holds the single pointer claim (`claimPointer('draw')`, `src/data/inputOwnership.js`) and **every** ambient scene selection handler — the shared tracking click gesture behind flights, military and CCTV, plus vessels, satellites, launches, fires, installations, bikeshare, radio, submarine cables, the bundled GeoJSON layers and the CCTV calibration gizmo — returns before picking. A vertex over an aircraft is a vertex, not a selection.
 - **The claim is a LEASE.** `claimPointer(owner)` returns an opaque token or `null`; `releasePointer(lease)` takes that token. A second claim fails even under the same owner name, because two live instances of one tool — an old one mid-teardown and its replacement — are two owners; releasing by name let the old instance free the claim its successor was holding, and every layer started selecting through the live session's vertices. A superseded lease now releases nothing.
 - **Cesium's own click actions are borrowed too.** The Viewer binds a selecting LEFT_CLICK and a tracking LEFT_DOUBLE_CLICK on its own handler, outside every layer and therefore outside the shared claim — guarding the layers alone still left a drawn vertex selecting the entity under it. Both are removed for the session and restored, as the same function objects, when it ends or the tool is destroyed.

 - **Modes, pins and the preview.** The mode is explicit: `image` (one pinned day, slot `a`), `basemap` (that day on the left of a swipe, the basemap on the right: slot `a` splits LEFT and there is no second layer) and `ab` (day `a` left, day `b` right). `setAssignment(slot, key | null)` / `toggleAssignment(slot, key)` pin and unpin; a day is in one slot at most (pinning it in the other slot moves it) and an empty day cannot be pinned. `setMode()` keeps both pins; `b` only drapes in `ab`. While the mode's first empty slot exists the focused day previews in it: a click at once, arrow keys after 250 ms of quiet (`FOCUS_DEBOUNCE_MS`, one timer, last day wins); an unprobed day is followed and previews when its probe says present, an empty or unknown day never drapes and the previous preview stays. A pin change drops the preview until focus moves again, and unpinning takes that layer off at once. `rankLatest` picks START HERE coverage first (a present HLS day whose footprints cover the box, or have none, beats a newer sliver), then newest with all granules ≤ 20% known cloud, then newest; slivers only as `partial`; else the newest non-empty VIIRS day; it is focused and previewed after each search when nothing is pinned. Escape clears the preview (`clearPreview()`), then cancels the box tool, then blurs — with SELECT BOX armed too, through the tool's `onEscape` interceptor wired in `createApplicationTools`. Pins, mode, box and split changes made in the panel are published with `adoptLayerParams`, never while a share link is being applied.
 - **Rendering.** `rendering.js` owns at most two GIBS layers on the host `src/maps/imageryHost.js` resolves: `viewer.imageryLayers` while the globe shows, the photoreal tileset's `imageryLayers` while it is hidden, or none (the panel says so). Layers are rebuilt on a new host, never re-parented. `MapSourceController.subscribe()` fires after every settled stack switch (silent switches and fallbacks included) and the layer rebinds on it. Tile requests pass a six-slot semaphore of our own (Cesium's global limits are untouched). Under `requestRenderMode` a deferred tile needs a later frame, but a deferral must never request one itself or a stalled tile keeps the scene rendering every frame: a request that finds the semaphore full asks for nothing (the settling request asks for one frame), and a tile Cesium itself deferred goes through one coalesced 250 ms retry. Thumbnails: three fetches at once, sixteen decoded images, least-recently-used where a `get` read is never a use; eviction keeps the probe result. The strip's visible window is probed around the focused card; the pinned and previewed days are probed wherever they sit, at the focused card's priority, so a pin restored or assigned off-screen still drapes.
 - **Esri surface and the swipe.** While any image is on the map (a preview included) the layer holds the map lease (`acquireImageryComparison`, owner `recent-imagery`, `esri-if-photoreal`): on Google 3D the map switches to Esri, because 30 m pixels over 3D buildings do not read, and Cesium's split only works on the globe. The lease is handed back, and Google 3D restored unless the operator changed maps meanwhile, when the last image leaves the map or the layer is disabled; the notice line says so while it holds. While a day is shown the imagery keeps Esri: a manual switch that lands on Google 3D is answered at once with a new lease under the same policy (`keepEsri`), the notice reads `Imagery stays on Esri · CLEAR to use Google 3D`, and the divider never suspends because of a map switch. It re-leases once per switch generation and only for a manual one (`MapSourceController#getSwitchOrigin()` is `manual` for an outside `setStack`, `automatic` for the controller's own fallback or recovery), never for the lease's own switch and never while releasing, so CLEAR and disable still return to Google 3D; a lease another owner holds stays refused. When Esri fails and the controller falls back to Google 3D on its own, the layer lets the lease go without restoring anything, both days drape on the tileset without a swipe and the guidance reads `Esri map unavailable · no swipe`; only the next manual switch to Google 3D takes Esri again, so a failing Esri map is never retried in a loop. Switching between globe stacks (Esri, OSM, Bing) only rebinds. On a tileset host both images drape without a swipe. The split control (`createImagerySplit`, labels A / B, or IMAGE / BASEMAP) exists only while a swipe is live, recentres on every new comparison (not while scrubbing the second day), except once for a split restored from a link. There is no keyboard shortcut (Space is the app's push-to-talk): SWAP (`#ri-swap`, in the controls row, its slot reserved and the button disabled while no swipe is live) trades the two sides, A to the right and B to the left, or the image to the right of the basemap, and a second click restores; the hint reads `Drag the divider · SWAP trades sides`. The swap is not in the share link, and every new comparison starts unswapped. One opacity applies to both drapes. Another owner holding the lease is reported and the images still drape.

 ### Split-flap status chips (August 2026)
 
-- The three status chips flip their LABELS over character by character when the text changes, like a departure board: `#global-loading-label` ("LOADING LIVE DATA" → "LOAD COMPLETE"), `#traffic-sync-label`, and `#cctv-sync-label` ("loading frames" → "camera grid ready"). All three route through `setSplitFlapText()` in `src/splitFlap.js`; there is no other writer of those three elements. The progress counters (`#*-sync-progress`, `#global-loading-detail`) are deliberately left as plain `textContent` — they tick several times a second, and flapping them reads as a slot machine.
-- `#global-loading-label` doubles as the universal top-center status banner, so anything routed through `_showGlobalStatusNotice()` flaps as well — in particular the share-link restore notices, of which "Shared military flight could not be restored — feed unavailable" is the longest at 63 characters. That needs no special case: `planSplitFlap()` compresses the stagger to hold the 620 ms budget (26 ms → 6.9 ms per column at that length), every column is reserved for the whole cascade, and `element.textContent` is the complete notice at every instant, so the `aria-live` region announces the whole sentence rather than a fragment. A notice deferred minutes past boot is equally safe: `ensureHost()` re-validates the shell on every call, and the long-lived `Text` node is never replaced.
-- **DOM text is the truth, and its node NEVER moves — do not "fix" this.** The first call upgrades a chip label into a permanent shell (`ensureHost`): a `.gev-flap-text` span holding one long-lived `Text` node, plus an `aria-hidden` `.gev-flap-cells` sibling. After that the ONLY text operation for the life of the chip is `node.data = next`. Nothing is reparented, so the label is never transiently empty and the `aria-live` region never sees a removal/reinsertion pair it could announce twice. `element.textContent` is the settled string at every instant, because the cells carry no text at all: both glyphs are CSS generated content (`::before` from `data-flap-prev` = outgoing, `::after` from `data-flap-next` = incoming), which never reaches `textContent`. This keeps QA pins honest and lets `_updateTrafficSyncChip`'s own `textContent !==` guard keep working. The shell is built on a tick where the text is NOT changing, so no real label change ever carries a structural mutation.
-- **No animation loop, and exactly ONE `setTimeout` per change.** CSS `animation`/`transition` only, triggered once per text change and staggered through a per-cell `--gev-flap-delay`. The single timer is the settle that strips the cells; the width ease ends on a `transitionend`/`transitioncancel` listener, never a second timer. Idle cost is zero, there is no periodic work, and nothing requests a Cesium render or takes a render-governor hold. `setSplitFlapText` is a no-op on unchanged text, which is required — the chips are repainted by a 60 ms and a 500 ms ticker.
+- The three status chips flip their LABELS over character by character when the text changes, like a departure board: `#global-loading-label` ("LOADING LIVE DATA" → "LOAD COMPLETE"), `#traffic-sync-label`, and `#cctv-sync-label` ("loading frames" → "camera grid ready"). ShellFeedback and CctvControls publish them to the `gev-status` store, and the scene chrome renders each label with `SplitFlapText.vue`, which plays the cascade `src/splitFlap.js` plans; there is no other writer of those three labels. When an owner is destroyed it publishes the label `stopped`, which rests it at once. The progress counters (`#*-sync-progress`, `#global-loading-detail`) are deliberately left as plain `textContent` — they tick several times a second, and flapping them reads as a slot machine.

The ONLY text operation for the life of the chip is `node.data = next`. Nothing is reparented, so the label is never transiently empty and the `aria-live` region never sees a removal/reinsertion pair it could announce twice. `element.textContent` is the settled string at every instant, because the cells carry no text at all: both glyphs are CSS generated content (`::before` from `data-flap-prev` = outgoing, `::after` from `data-flap-next` = incoming), which never reaches `textContent`.

Idle cost is zero, there is no periodic work, and nothing requests a Cesium render or takes a render-governor hold. An unchanged label is not republished, which is required — the chips are recomputed by a 60 ms and a 500 ms ticker.
 - **Only what was visible flaps away.** An interrupted cascade (A→B cut short by C) derives each column's outgoing glyph from `visibleGlyphs()` — what that column is actually SHOWING at that instant, which for a column whose stagger has not elapsed is still A, not the pending B. `FLAP_TURN_RATIO` must track the `gev-flap-out`/`gev-flap-in` keyframe crossover in style.css.
 - **Columns never renumber mid-cascade — do not "optimise" this away.** For the whole cascade the board keeps one column per index of the LONGER string, each holding its own width; a column the new string does not reach flaps to a BLANK in place (`data-flap-next=" "`) rather than collapsing. Collapsing stacks the absolutely-positioned outgoing glyphs on one x AND lets a later glyph slide into an earlier column, which makes `visibleGlyphs()` lie and the interrupt rule flap the wrong glyph away. Pinned by "a cleared column holds its place instead of letting later glyphs slide left".
 - Length changes are eased, never snapped, and the ease is placed so it never fights the flaps (`.gev-flap-sizing`): a GROWING label reserves its columns as the cells go in and eases at the START; a SHRINKING one holds full width for the whole cascade and eases at SETTLEMENT.

Expanding Layers or Authoring keeps the active panel in the available upper-left corridor with internal scrolling; it does not cover the Contact card, lower Cockpit controls, or Cesium credit line. Outside Cockpit the hidden card does not alter the normal corridor.
 - **Cockpit Context scope:** the 250 km radius applies to the air/sea proximity cohorts. Installation counts come only from the currently loaded viewport and are labeled `CURRENT VIEWPORT ONLY` in the cockpit as well as the normal Context panel; neither surface presents them as a complete 250 km installation survey.
 - **Cockpit camera anchor:** first-person mode does not write feed-boundary corrections directly into the camera. A cockpit-only inertial anchor advances from the selected aircraft's displayed course and speed, then converges toward the authoritative delayed track with correction capped below forward motion. The displayed kinematics are derived from the same consecutive fix segment as the rendered position, with raw feed speed/course used only as fallback; a transient zero/missing feed speed therefore cannot freeze a visibly moving aircraft after layer enable or a map/cockpit handoff. Rendered altitude continues to come from that interpolated track position. Late ADS-B fixes and short render stalls can remove drift without accelerating or reversing the view. Camera placement runs before scene update/culling at a bounded 20 Hz so a moving cockpit does not force Photoreal 3D Tiles to retraverse on every display frame; textual instruments update at 10 Hz and context/layout work at 4 Hz. Every far Cockpit contact pip shares one stable Cesium texture-atlas entry and skips unused screen-projected course calculations, while only in-range 2D aircraft silhouettes pay the screen-projected rotation cost; ambient glTF collections are hidden/retained rather than synchronously destroyed at cockpit entry, and context rails lay out only on explicit content/state changes and viewport resize. The deliberate 15/30-second layer interpolation delays and per-Cesium-frame position caches remain unchanged.
 - **Cockpit route, vision, and view controls:** visible on-screen `COCKPIT`, `RESET`, and `EXIT COCKPIT` controls replace reliance on the `C` shortcut. RESET uses the same canonical globe route as the map and voice actions, exits Cockpit, and releases its camera ownership rather than exposing the hidden map-style top action. When the tracked commercial flight has a plausible ADSBDB route, the top of the right briefing rail shows a compact `FROM → TO` airport strip and the visor shows a centered estimated-destination chevron with its relative bearing; its destination label rounds to whole degrees in 000–359, wrapping rounded north to 000° while the chevron continues to use the relative bearing independently of label rounding; absent or implausible route data hides the strip and cue rather than guessing. The cockpit-local vision control is an interactive `PREV / CURRENT / NEXT` carousel over `NORMAL`, `CRT`, `NVG`, `FLIR`, `ANIME`, and `NOIR`; its previous/next actions wrap, and activating the current value advances to the next style. Cockpit enters on the active map preset, so a Cyber FLIR map opens Cockpit on FLIR while Normal remains a distinct option instead of producing a second FLIR entry. Cockpit choices temporarily activate the existing Cesium post-process stages, while exiting Cockpit through either EXIT or RESET restores the pre-entry map style. The regional-news page uses a free Google News RSS locality query first, with the existing GDELT query retained only as a fail-soft fallback; linked headlines remain reporting, not verified incidents or risk intelligence.

 A module the server, tools or other portable code also imports must not load the catalogs: it imports `msg` from `src/i18n/marker.js`, which only marks the text, and the UI translates it with `t()` where it shows it. (Older modules keep a local `const msg = (text) => text`, which works the same.)
 
+Vue views call the same `t()` and `tn()`. The page's vue-i18n instance (`src/ui/i18n.js`), installed in every view, holds the active locale, and `t()`, `tn()` and the formatters read it from there, so a view that translates while rendering renders again when the locale changes. Views don't use vue-i18n's own `t`: English is the key, `context` picks an entry and plural forms follow `Intl.PluralRules`, which only Core's functions do.
+
 `msg()` exists for two reasons. `npm run i18n` finds messages only as string literals inside `t(…)`, `tn(…)` and `msg(…)`, so `t(FEED_STATE_LABELS[state])` alone tells it nothing. And a `t()` call at module load runs before the page has picked its language, so it would freeze the English.
 
 ## Markup
 
+Vue views translate in the template, so their text renders in the active locale:
+
+```vue
+<span>{{ t('Normal') }}</span>
+<button :title="t('Pin visual presets')">…</button>
+<option value="all">{{ t('All', { context: 'radio tag' }) }}</option>
+```
+
+Static page markup that no view renders (the loading screen in `index.html`, a host's own markup) opts in with attributes instead, and `npm run i18n` rejects them in a Vue template:
+
 ```html
 <span data-i18n>Normal</span>
 <button title="Pin visual presets" data-i18n-title>…</button>
 <input placeholder="Search any location..." data-i18n-placeholder />
 ```
 
-`data-i18n` replaces the element's text, so put it on the element that directly holds the text, never on a parent with child elements. `data-i18n-title`, `data-i18n-aria-label` and `data-i18n-placeholder` translate that attribute. `data-i18n-context="radio tag"` gives the element's text a context, the catalog entry `radio tag|All`, as `t('All', { context: 'radio tag' })` does in code. Markup is translated once at boot, and switching language reloads the page. A module that holds work a reload would lose (an unsaved edit, an open session) registers it with `registerUnsavedWork(() => busy ? msg('unsaved …') : null)` from `src/i18n/index.js`, and the language picker asks before reloading.

+The language picker switches in place, without a reload. A view that calls `t()` while it renders follows by itself. Code that translates text and hands it on (to a store, a published view object, a layer's state, a DOM node) must word it again when the language changes:
+
+- **Present again.** `onLocaleChange(listener)` from `src/i18n/index.js` calls the listener after each change and returns the function that removes it; call that at teardown. The listener presents the view again from what it keeps, as `layerPanel.js` and `cockpitController.js` do.
+- **Keep the English, translate when presenting.** Store `msg()` text or a function that words it, not its translation: the voice control takes `update(part, { text: () => t('MIC') })`, the scene director's status and the SDR receiver's messages keep such functions, and `imagerySplit.js` takes its titles that way.

+Owners that present UI do so through Vue: they publish plain view objects to a
+Pinia store in `src/ui/stores/`, views in `src/ui/views/` render them, and user
+actions return through the handlers the owner connects to that store. See
+[Building UI](../CONTRIBUTING.md#building-ui).
+
 Owners receive named services, elements, operations and readers. They do not
 receive the application shell itself. Readers resolve a replaceable collaborator
 at use time; operations cross an ownership boundary without copying its state.

+# Vue migration
+
+The application UI moves from static templates plus imperative DOM wiring to
+Vue 3 components with Pinia stores. The migration keeps the experience the
+same: element ids, classes, the global stylesheet, translations, keyboard
+shortcuts, voice actions, share links and the phone layout all behave as
+before. The one intended change is the panel rail described below.
+
+## Goals
+
+- Views are Vue single-file components; state that several views read lives in
+  Pinia stores rather than in DOM classes.
+- The owners listed in [UI-OWNERSHIP.md](UI-OWNERSHIP.md) keep their
+  responsibilities. A component replaces DOM construction; it does not add a
+  second owner of the same state.
+- Public methods used by layers, scene playback, voice and host applications
+  (`setPanelCollapsed`, `setContextMode`, `setStyle`, share and location
+  subscriptions) keep their signatures.
+- Ids and classes used by browser QA and host applications stay stable until a
+  host can use an explicit extension point instead.
+
+## The panel rail
+
+Each desktop sidebar gets a floating icon rail that lists every panel available
+on that side. Selecting an icon opens that panel; selecting it again closes it.
+One panel is open per side at a time, so the rail replaces the accordion
+stacking. Panels that are not available in the current mode (for example
+Weather before a weather layer is active) are shown disabled or omitted as the
+panel's own availability rule dictates. The rail hides with the rest of the
+chrome in Cockpit, scene playback, recording and the clean view.
+
+Phones keep the existing bottom tab bar and sheets; the rail is desktop only.
+
+Voice and keyboard openings go through the same panel store, so they follow the
+one-panel rule too. Share links continue to record which panels are open.
+
+## Component kit
+
+`src/ui/kit/` holds the generic components: `UiRail`, `UiTooltip`, `UiIcon`,
+`UiButton`, `UiPanel`, `UiSegmented`, `UiSlider`, `UiChip`, `UiSelect`,
+`UiBadge` and `UiEmpty` so far, with more joining as the controls they serve
+are converted. One component
+serves every use of a control, with props for the differences (`UiPanel`'s
+`sideways`, `glow`, `scroll`), rather than a copy per panel. The components
+are styled by the existing stylesheet and custom properties; a kit class such as
+`ui-button--icon` carries no Core style yet, and a converted control keeps
+its own classes beside it. They contain no application state.
+`UiPanel` takes a `title`, slots and `v-model:collapsed`, but its
+`collapsed` drives only the button and `ui-panel--collapsed`: the root's
+`collapsed` class, which hides the body, is drawn at once by `v-panel-state`
+from the panel chrome store, and there is no `closable`, since Core's panels collapse rather than close.
+`UiSegmented` adds `keyboard` (`none`, `arrows`, or `radio` with
+Home and End), since each of Core's groups keeps its own keyboard policy, and
+`itemClass`/`activeClass` for Core's segment classes. A key moves focus at
+once and asks for a change only when it lands on another option. Every
+segmented group in Core is a `UiSegmented`; the old `segmentedControl.js`
+adapter is gone.
+`UiButton` adds `pressedClass`, Core's class on a pressed toggle (most use
+`active`); its pressed classes toggle through `classList`, so a class other
+code adds (a voice highlight) survives a press. Every pressed toggle in the
+views is a `UiButton` except Bhote Koshi's cinematic button and the
+tilt-map button, whose owners still write their state into the DOM. Core's
+pressable chips and pills (rail card chips, map sources, cities and places)
+are `UiButton`s too; `UiChip` is a non-interactive label chip, used by
+the voice card.
+`UiSelect` renders the bare native select (Core's labels sit outside it or
+come as an `aria-label`) with `v-model`, `options` and `disabled`;
+options that carry their own attributes come through the slot, a caller's
+`@change` still reaches the select, and `hold` works as in `UiSlider`.
+Without `hold`, a select takes its model back after its own change renders,
+so a pick its owner refuses goes back; an owner that answers later (the SDR
+gain) takes `hold`. Every select in the views is a `UiSelect`.
+`UiBadge` takes a `tone` and carries Core's `gev-status-badge`; its
+density variants and colours stay caller classes, and it renders the CCTV
+source and calibration badges and the rail card badges. `UiEmpty` takes
+a `title` and `hint`, but Core's empty states are one line, so the title
+is the text itself rather than a bold heading; the Scene shot list, mission
+roster and imagery strip use it. The locale picker's and the mission tables'
+empty rows stay a paragraph and table cells.
+`UiSlider` keeps the native range input rather than drawing a
+`role="slider"` track, so Core's keyboard, form behaviour and styling stay;
+it takes `v-model`, `min`, `max`, `step` and `disabled`, emits a
+number, and adds `hold` (never rewrite a focused handle, and take the model
+back on blur) and `unstyled` (the browser's own range, as Bhote Koshi's
+are, without Core's slider surface). A caller's own input, change and blur
+handlers still reach the input, and a null model leaves it as it is. It is
+a functional render-function component, so the portable `./ui/input` rows
+use it without a component compiler. Every range in the views is a
+`UiSlider` except the radio tuner's: its owner moves the handle back to the
+selected station on a drag's first input without changing the slot, which
+a functional component would not render again.
+
+Controls share one skin, so every panel reads the same. Every scrolling
+surface carries the kit's `.ui-scroll`, which draws the thin
+themed scrollbar from `--scroll-thumb` and `--scroll-track`; the Cyber theme
+sets those two tokens, and Cockpit's HUD windows keep their accent tint. A
+surface without it would draw the platform's light scrollbar, because the
+page declares no dark `color-scheme`. Selects and number fields are
+`.gev-field`, which draws its own chevron in place of the platform's arrow
+and keeps native spinners dark; ranges are `.gev-quantitative-slider`, with
+a feature supplying only its accent.
+
+## Phases
+
+1. **Foundation.** Vue, Pinia and the Vite Vue plugin join the browser build
+   (`build/vite.js`, so host applications receive them too). One Vue runtime is
+   created by the shell (`src/ui/vueRuntime.js`) with one Pinia instance that
+   every view shares; disposing the shell unmounts them. Stores are added
+   when a view needs one, mirroring state an owner already publishes, so
+   there is never a second owner of the same state.
+2. **Rail.** `PanelChrome` enforces one panel per side; the panel store
+   mirrors each side's panels and the rail renders from it. The rail panels
+   are `RailPanel`s: the kit's `UiPanel` drawing Core's panel markup, bound to the `gev-panel-chrome`
+   store, with their titles rendered by `t()` rather than `data-i18n`. Each panel's
+   collapse button, the dock tray toggles and the
+   dock pins render the open and pinned state PanelChrome presents to the
+   `gev-panel-chrome` store, and their clicks call it there. Each panel's
+   root draws its own state from there too (`v-panel-state`: `collapsed`,
+   `dock-pinned`, `dock-pinned-top`, `layout-auto-collapsed`,
+   `accordion-collapsed`): PanelChrome, the rails and the accordion present
+   it rather than writing classes. The directive applies it in a synchronous
+   watcher, not on Vue's next render, because the rails measure a panel in
+   the same task that opens or closes it. PanelChrome and its preference
+   restore, and the phone shell, read a panel's state back from the store
+   (`_shownPanel`; the markup's classes before its first presentation), so
+   once a panel is presented a class written outside the store no longer
+   counts. The rails, the accordion and the hover disclosure
+   (`panelDisclosure.js`), which act within the same task as a layout, read
+   the classes the directive has just drawn. Done.
+3. **Panels.** Each template and its wiring become a component, keeping ids,
+   classes and CSS; text a template renders with `t()` drops its `data-i18n`
+   marker. The page places each view with a
+   `.gev-view` host (`display: contents`), and `mountApplicationViews()`
+   (`src/ui/views/index.js`) renders the view into it before the page is
+   translated and wired. `createApplication()` calls it too, removing the
+   hosts of any views its `omitViews` names. Views belong to the page and are
+   unmounted only when a later call omits them. The loading screen is static markup in the page so it
+   paints before any script runs. Markup
+   tests read `renderApplicationHtml()` from `src/testSupport`, which renders
+   the views on the server. Templates compile with Vue's `preserve`
+   whitespace, which keeps the whitespace between elements as a single
+   space, so a view renders as its template did; no view markup sits under a
+   `white-space: pre` rule. Application views (`src/ui/views/*View.vue`) are
+   kept out of Prettier; other components are formatted with strict
+   whitespace sensitivity, so their source spacing is what renders. The
+   markup has moved, unchanged:
+   every template except the loading screen is a view.
+
+   Next each view takes over its wiring: markup an owner builds with
+   `createElement` becomes component markup that renders from a Pinia store
+   the owner publishes to, and user actions come back to the owner through
+   the store, so the owner keeps every decision. Component text uses
+   `t()`, which follows the locale as the view renders; the views carry no
+   `data-i18n*` markers, which `npm run i18n` rejects in a template. Shared builders become components first and
+   keep their imperative entry points until their owners are components:
+   the rail cards, card blocks and timeline (`src/ui/rail/`) render through
+   Vue's synchronous `render()` behind `createRailCards()`,
+   `createRailCardBlocks()` and `createRailTimeline()`. Order: Scenes (done: `SceneOptions` and
+   `SceneShotList` over the `gev-scenes` store; the panel's buttons, status
+   line, progress bar and the runtime chip render the panel SceneControls
+   presents there, and the buttons and file chooser call its actions), Weather (done: the owner
+   renders `WeatherReadout` from the view it computes), Recent imagery
+   (done: `RecentImageryReadout` and its day cards, the same way),
+   Street level (done: `StreetLevelPanel` renders the `gev-street-level`
+   store that `StreetLevelControls` publishes to; the controls keep their
+   listeners, EXPAND, focus and resizing), CCTV (done: `CctvPanel` renders
+   the whole panel from the `gev-cctv` store, including the camera picker,
+   the inline pose editor, the frame preview, source badge and typed
+   summary; `CctvControls` keeps its listeners, the frame requests and the
+   live video surface), Layers (done: `LayerPanel` presents each row and
+   renders `LayerRows` synchronously; keyed chips and list items keep focus
+   through the refresh their own click triggers, and clicks re-read the live
+   descriptor before acting), Display (in progress: `DisplayPanel` renders
+   the HUD, Sonar, Scope, Celestial, detection, bloom, sharpen and the
+   active style's parameter sliders from the `gev-display` store, which
+   VisualSettings publishes to and answers the sliders through, and the 3D
+   aircraft group, the Draw controls and the imported file list, which
+   AircraftDisplay, the draw tool and the file import publish beside it;
+   the controls call DisplayBindings, the draw tool and the file import
+   through the store's `connect`/`act`, the newest owner of an action
+   answering it; `GeoImport` hands keyboard focus on before a focused row
+   goes, with `v-focus-safe-children`; the
+   style parameter rows render through Vue behind `createStyleParameters()`,
+   as a render function so the portable `./ui/input` entry needs no
+   component compiler; the other groups follow one owner at a time),
+   Context and Radio (in progress: `RadioPanel` renders the directory row,
+   station card, transport, volume and playback line from the `gev-radio`
+   store that RadioControls publishes to and whose controls it answers
+   through the store's `connect`/`act` (the shared `createOwners()`; a
+   refused station tag gets the kept tag back from `act`), and `SdrCard` the
+   local RTL-SDR card that LocalSdrControls publishes beside it and answers
+   the same way; fields a person edits take their value through
+   `v-field-value`, which never writes a focused field;
+   `RadioTuner` renders the directory tuner, where RadioControls keeps the
+   drag and its slot, takes the slider's pointer, key and value events
+   through the store and publishes the band, readouts, slider and needle,
+   and the component lays out the tick tape against the dial's measured
+   width and lays out the snapped needle before it drops the drag class;
+   `ContextView` renders the mode switch and the nearby sites
+   search from the `gev-context` store, which ContextControls reaches only
+   through its `publish` option, so `./ui/context` needs no Vue;
+   `AwarenessPanel` renders the Contacts panel that the awareness layer
+   publishes through `subscribePanel()`, the first layer to hand its rail
+   content to a view, and `MissionRoster` and `MissionDetail` the Space
+   Missions roster and selected mission that the launches layer publishes
+   the same way), the command dock (in progress: the style buttons, the
+   dock's style mini status and the ACTIVE STYLE corner render the style
+   VisualSettings publishes to the `gev-display` store; the buttons keep
+   their owner's listeners; the map source chips and status badge render
+   what `createMapSourceControls()` publishes beside it, so `./ui/maps`
+   needs no Vue; the location tray's city and landmark pills, mini status
+   and search error render what `LocationControls` publishes to the
+   `gev-location` store, and the search field keeps its listeners; beside
+   the voice control, the dock teleports each voice pointer reticle to the
+   body where its `PointerReticle` presents it in the `gev-pointer-reticle`
+   store), the phone shell (`PhoneTabBar` renders the tabs and open sheet the shell
+   publishes to the `gev-display` store, teleporting the tab bar and sheet
+   backdrop to the end of the page from the first publish until the shell
+   is destroyed; the shell takes their clicks from the document), the
+   imagery dividers (`ImagerySplitView`, in the scene chrome, teleports each
+   before/after divider that `createImagerySplit` publishes to the
+   `gev-imagery-split` store to the body; the split keeps the
+   drag, keyboard, CSS position and scene split), the status chips
+   (the top-center loading status and the road network and camera grid
+   chips render what ShellFeedback and CctvControls publish to the
+   `gev-status` store; `SplitFlapText` plays the departure-board flip that
+   `splitFlap.js` plans, writing only the label's one text node; the toast
+   renders what each owner's `createToast()` publishes there, on that
+   owner's own timer, and the title bar's FPS readout what
+   `createFrameRateMonitor()` publishes), the globe actions
+   (`GlobeActions` renders the top-center bar; its clear, share, tilt,
+   north-up and reset buttons, and the cockpit's reset, call the shell
+   through the `gev-globe-actions` store, which also carries a clear or a
+   reset under way and the camera's tilt and heading
+   that `bindCameraOrientationControls` publishes each drawn frame it
+   changes, which only `GlobeCompass` renders; an owner publishes only
+   while it answers the button, so a shell replaced by a newer one leaves
+   its state alone), the recording safe frame (the scene chrome renders
+   the frame `RecordingControls` publishes to the `gev-recording` store),
+   the Scene actions panel (`SceneInteractions`
+   teleports what the scene interactions owner publishes to the
+   `gev-scene-interactions` store into the viewer's container; the owner
+   keeps the pick handler and focuses the picked action), the data-pack
+   attribution cards (`DataPacks` teleports what the data-pack presentations
+   publish to the `gev-data-packs` store into the viewer's container and
+   stops a removed card's player), the wind inspection marker
+   (`WindInspectionMarker` teleports the marker into the wind layer's
+   container where `createWindInspectionMarker()`, now in
+   `src/layers/wind/inspectionMarker.js` so the portable `./tools` entry
+   needs no Vue, places it after each rendered frame; an unchanged frame
+   publishes nothing), the Space Missions replay vehicle
+   (`MissionReplayOverlay` teleports into the globe container what the
+   launches layer presents through `subscribeReplayOverlay()`, which the
+   application shell publishes to the `gev-mission-replay` store, so the
+   portable `./layers/launches` entry needs no Vue), the Bhote Koshi
+   reconstruction panel (`BhoteKoshiPanel`, last in the context rail,
+   renders what the event layer publishes to the `gev-bhote-koshi-panel`
+   store: each control's text, hidden, disabled, value and attributes as
+   the layer writes them, unchanged frames sending nothing; the rail takes
+   `bhote-event-active` while it shows), the full-globe celestial ring
+   (`CelestialRing` teleports into the globe container what `CelestialRing`
+   in `src/celestialRing.js` publishes to the `gev-celestial-ring` store and
+   hands its two canvases back for the owner to paint; the application shell
+   passes the store in, so the keyhole helpers other packages import need no
+   Vue), the screen-space map annotations (`ScreenAnnotations` teleports to
+   the body the board the screen annotation renderer publishes to the
+   `gev-screen-annotations` store after each rendered frame: each mark's SVG
+   parts as attribute records, the fading marks until they leave; the view
+   hands back the callout text and mark groups the renderer measures, and
+   the tracked-entity fade is measured once the frame is in the document;
+   the styles it injected now live in `src/ui/styles/annotations.css`), the
+   visible map target list (the scene chrome renders the buttons and status
+   the world overlay presents through `subscribeWorldOverlayActions()`, which
+   the application shell publishes to the `gev-world-overlay-actions` store
+   and answers with `activateWorldOverlayAction()`; the module needs no Vue
+   for the portable transit entry, and its card and detection canvases stay
+   painting surfaces it draws on, like the Cesium canvas), the Global
+   Context compass and contact bearings (`AwarenessDirection` teleports into
+   the globe container what the awareness layer presents through
+   `subscribeDirectionOverlay()`, which the application shell publishes to
+   the `gev-awareness-direction` store, so the portable `./layers/awareness`
+   entry needs no Vue), the Intel HUD (the `intel-hud` view renders
+   `#intel-hud`, its corners, edges and bottom bar from the `gev-hud`
+   store, which IntelHUD publishes to through its `publish` option: the
+   readouts, the typing summary, the REC blink, visibility, layout variant
+   and style colors; the vessel layer presents the selected vessel's
+   readout through `src/hudReadouts.js` instead of writing into the HUD),
+   the first-run mission launcher (the welcome view renders the card's
+   visibility, busy state, status line, copy and scroll fade from the
+   `gev-first-run` store that `initFirstRunExperience` publishes to, and its
+   choices, DISMISS and "Don't show this again" call the launcher's
+   controls; a refused save hands the tick back to the view to revert. The
+   launcher still reads the rendered card for its hit test, keyboard trap,
+   focus and overflow measurement), then
+   Cockpit (in progress: `CockpitBriefing` renders the briefing card's
+   pages, cycle toggle, regional news and local conditions, and
+   `CockpitContext` the Contact card's scope, navigation, counts, nearest
+   contact and weather toggle, `CockpitView` the instruments, destination
+   arrow and vision selector, and `CockpitRoute` the flight plan card, from
+   the `gev-cockpit` store that the Cockpit controller publishes to,
+   starting from `cockpitBriefPages.js`, `cockpitContextState.js` and
+   `cockpitInstrumentState.js`, which both read; the odometer readouts
+   (`CockpitRollingValue`) keep their throttle and roll in
+   `cockpitRollingValue.js`. `CockpitSignalList` renders the live signal
+   rows; `v-focus-safe-children` turns Vue's move of the focused row into
+   moves of the rows around it, and hands focus to the shown briefing tab
+   before the focused row is removed, so a keyed list reorders several times
+   a second without dropping keyboard focus. The instruments publish on
+   every HUD update (about 10 Hz); in a dev build their Vue patch costs
+   about 0.5 ms, close to the DOM writes it replaced. The controller also
+   publishes which surfaces are shown: the entry button and TR-3B chip in
+   the Context panel, the HUD with its exit and reset buttons and briefing
+   card, and the Contact card. Focus moves to the exit button, and back to
+   the entry, only after Vue renders them. The cards' collapse is part of
+   that presence too: each card's `data-collapsed` and its toggle's words
+   and icon render from it. The controls keep the controller's listeners,
+   and the cards' layout stays with the controller, which reads their
+   visibility when it lays them out. Its layout pass publishes the utility
+   strip's measured fit (the HUD's anchor and height limits, whether only the
+   expanded control fits and which control is hidden from assistive
+   technology), which `CockpitView` and `CockpitUtilityControls` render; the
+   briefing and Contact cards' positions stay imperative, because the same
+   pass measures them straight after writing them.
+   `CockpitUtilityControls` renders the Display
+   and Radio launchers, which popover is open and the compact Radio
+   controls from the `gev-radio` store that RadioControls publishes to and
+   answers through. The Cockpit display portal publishes the Display
+   popover's slots to the `gev-display` store while Cockpit is on, and
+   `DisplayPanel` teleports its HUD, Detection, Parameters and 3D groups into
+   them and back; the portal keeps each surface's scroll position and puts
+   back focus the move dropped).
+   Layers that write into the right rail directly gain a slot instead.
+
+4. **Cleanup.** The build-time template expansion is retired: `index.html`
+   lists the view hosts and the loading screen itself. Every owner that
+   showed UI state through hand-written DOM writes now publishes to a store
+   that a view renders, apart from the imperative parts this document
+   records surface by surface; [Building UI](../CONTRIBUTING.md#building-ui)
+   now requires the pattern for new UI. The page-level markup tests read
+   `renderApplicationHtml()`, the real views rendered on the server, and new
+   tests mount components; three tests still read a `.vue` file's source
+   (`cyberTheme`, `panelStorageDocs`, `geoFileImport`). The views translate with `t()`
+   while rendering, and vue-i18n holds the locale they read; the attribute
+   translation pass is left for static page markup (the loading screen and a
+   host's own markup). An explicit API for hosts to register panels and rail items is
+   deferred until a host adds one: no host does today (the hosted
+   application's account interface is its own markup), and the first such
+   panel, the hosted timeline, will shape it.
+
+## Verification
+
+- Unit tests: stores and components run under `npm test`. Single-file
+  components are compiled by a test loader; component tests render with
+  `@vue/test-utils` and `happy-dom`. `npm test` registers the loader; to run
+  one file that reaches a component (including anything importing the
+  shell), use `node --import=./build/registerVue.js --test <file>`.
+- Never pass happy-dom nodes to `assert.equal` or `deepEqual`: a failure
+  prints both operands, and a node reaches the whole page and window, which
+  runs the process out of memory. Compare nodes with `assertSameNode()`
+  (`src/testSupport/domAssert.mjs`).
+- Panels lifted out of a view keep its verbatim markup in
+  `src/ui/views/panels/`, which Prettier leaves alone like the views.
+- Visual parity: before/after screenshots of every panel at desktop and phone
+  widths, in the default and Cyber themes, with the rail as the only expected
+  difference.
+- Browser QA: the selector-based `scripts/qa-*.mjs` suites keep passing.
+- `npm run format:check`, `npm run check:boundaries`, `npm run i18n` and
+  `npm run build`.

 ## Digits and direction
 
 - **Western digits (0–9)**, as in the catalog. The HUD reads like an instrument panel, and mixing ٠–٩ with Latin codes and coordinates misreads. `intlLocale('ar')` in `src/i18n/locale.js` passes `ar-u-nu-latn` to every Intl formatter, so browsers that default to Arabic-Indic digits for an Arabic region still show 0–9.
-- **Right to left.** `ar` is in `RTL_LOCALES`, so the page gets `<html dir="rtl">`. The title, style indicator and both rails swap sides; the dock and the corner row reverse. The intel HUD (classification block, MGRS, coordinates, GSD) stays a left-to-right instrument overlay; its translated lines read right to left inside it. Media transport (previous / play / next) and the radio dial stay left to right, as on any player. Layout rules: `src/ui/styles/rtl.css`.
+- **Right to left.** `ar` is in `RTL_LOCALES`, so the page gets `<html dir="rtl">`. The title, style indicator, both panel stacks and their icon rails swap sides; the dock and the corner row reverse. The intel HUD (classification block, MGRS, coordinates, GSD) stays a left-to-right instrument overlay; its translated lines read right to left inside it. FM seek and the radio dial stay left to right, as on any receiver. The rails' screen-reader names follow the mirrored layout: «Left panels» is «اللوحات اليمنى». Layout rules: `src/ui/styles/rtl.css`.
 - Latin runs inside Arabic sentences (product names, codes, `{placeholders}` filled with English data) are isolated by the bidi algorithm; write them as plain text, without manual direction marks.
 - Position counters: a translated counter says «من» («القناة {index} من {total}», «الإطار {index} من {total}»); a spaced slash between two isolated numbers swaps them in right-to-left text. Counters the code builds from bare numbers (`01 / 25`, `1 / 3`) are shown left to right by `rtl.css`.
 - Code stays left to right: the JSON fields of the scene editor are LTR in every language.
