   **Quebec is thinly represented**, and that is upstream rather than a filter here: the province runs its own Info-Smog program, so only a handful of Quebec stations appear in ECCC's national feed. The reporting station count also varies hour to hour as stations report or fall silent.
 
 - **Via Lietuva / Eismoinfo (Lithuania).** Public road-camera catalogs and periodically updated still images from [Eismoinfo](https://eismoinfo.lt/), credited to Via Lietuva / eismoinfo.lt in the app. **Off by default.** The camera endpoints are the eismoinfo.lt website backend and are not among the services listed in Via Lietuva's [open-data statement](https://eismoinfo.lt/eismoinfo-backend/content?id=44), whose conditions are attribution and reuse on the same terms. Until the statement is confirmed to cover the camera photos, the pack loads only when an operator sets `CCTV_LITHUANIA_ENABLED=1`; with the flag unset, empty or any other value, the server makes no request to Eismoinfo. `eismoinfo-backend/camera-info-table` is joined by ID to `layer-static-features/VKR`. Without `lks=true`, the latter returns WGS84 `[latitude, longitude]`; the table's `x/y` instead use LKS-94 metres. Only the official HTTPS `/eismoinfo-backend/image-provider/camera/last?id=…` image endpoint is registered. Catalogs use the shared 15-minute cache; frames are fetched on demand and never bundled or archived. These are periodic snapshots, not continuous video. Camera headings are low-confidence estimates. No API key is required. `CCTV_LITHUANIA_MAX_SOURCES` defaults to 400.
+- **Freeway Bureau, MOTC (Taiwan).** National freeway cameras from the Freeway Bureau's keyless [CCTV static table](https://tisvcloud.freeway.gov.tw/history/motc20/CCTV.xml) in the MOTC 2.0 standard, refreshed daily and fetched at runtime (never bundled). Freeway Bureau traffic data is published under the [Open Government Data License, Taiwan (Version 1.0)](https://data.gov.tw/license), which permits reuse, including commercial reuse, with attribution; the app credits the Freeway Bureau, MOTC, names the dataset and links the licence, as its attribution exhibit asks. The table publishes each camera's MJPEG stream on one of four official camera servers (`cctvn`, `cctvn5`, `cctvc`, `cctvs` under `freeway.gov.tw`). The frame proxy relays single images, so each published stream URL is mapped to the same server's single-JPEG path for the same camera number (`/abs2mjpg/bmjpg` → `/abs2mjpg/jpg`, `/live-view/mjpg/video.cgi` → `/live-view/jpg/image.cgi`); only those exact HTTPS pairs are registered, and the still path is not itself listed in the table. These are on-demand snapshots, not continuous video. Camera headings are low-confidence estimates. No API key is required. The table host does not answer from some networks outside Taiwan (the camera servers do); there the pack is empty, logs one warning and retries hourly. On by default; `CCTV_TAIWAN_ENABLED=0` skips the pack, and `CCTV_TAIWAN_MAX_SOURCES` defaults to 600 (bounded to 1–2000).

 - **Catalonia (Servei Català de Trànsit) cameras.** The camera list is the keyless `https://www.gencat.cat/transit/opendata/cameres.xml` WFS/GML feed, fetched over https with redirects refused and the body read capped at 1 MiB, since the list decides ids, coordinates and which allowlisted frame path is proxied. It carries a `font` field naming the real publisher per camera; this pack keeps SCT's own highway cameras plus hotlinked Barcelona (IMI) and Terrassa municipal cameras (~130 total), each confirmed to return a real frame, so frame URLs are checked against a small host allowlist (`mct.gencat.cat`, `www.bcn.cat`, `emap.terrassa.cat`) rather than one pinned origin (a link carrying `user:pass@` userinfo or an explicit port, or pointing outside that host's frame directory, is rejected even on an allowed host; an SCT `sctidcam` must be a bare `.gif`/`.jpg` filename), and every non-SCT camera carries its real owner as a `credit` shown beside the shared `provider`. The feed carries no compass heading, so every camera loads at low heading confidence (same as TfL and Fintraffic). SCT's own feed link (`RenderService`) needed a workaround: it always 302s to a second endpoint (`TransitCamera`) on a Location the upstream hardcodes as plain http even when requested over https — refused by `fetchWithinHost`'s same-origin (scheme-included) redirect policy — and separately, `mct.gencat.cat`'s TLS setup fails the handshake with Node's fetch outright (`ERR_SSL_WRONG_SIGNATURE_TYPE`) even though other HTTP clients complete it. The loader therefore builds the `TransitCamera` URL itself, over plain http, from `RenderService`'s `sctidcam` id, rather than registering the (broken) upstream link — the only transport this one host actually serves to this runtime. Camera ids are built from the SCT camera file or the partner image path, not the feed's `fid` (which embeds an upstream server-start stamp and changes on every upstream restart), and rows the feed lists more than once collapse to one camera. The feed carries no camera status field, so a camera its publisher has taken offline still registers and shows the publisher's own "image unavailable" still (SCT and Barcelona both serve one with HTTP 200), the same as other packs without a status field. Frames are fetched at request time and never stored or redistributed. The feed itself states no licence; the pack relies on the Generalitat de Catalunya open-data portal's terms for this dataset (the licence and attribution above). Disable with `CCTV_CATALONIA_ENABLED=0`.
 - **King County road cameras.** Keyless. The camera list is one public ArcGIS FeatureServer GeoJSON query (King County DOT Road Services, "King County and WSDOT Traffic Cameras"). The `outFields` list is explicit on purpose: the layer also carries asset-administration columns — including staff names — that are never fetched. Only live, active cameras with frames on the county's own `info.kingcounty.gov` image handler are registered (the feed writes `http://`; the handler serves HTTPS, so URLs are upgraded and pinned before registration). WSDOT-owned rows in the layer are skipped because their frames are WSDOT-hosted, outside the pinned image origin; partner-city cameras hosted on the county image handler (e.g. Newcastle) name their owner as the per-camera credit. The layer publishes no facing, so headings use the shared id-hash fallback at low confidence. Uniquely, the county publishes each camera's hardware `Manufacturer`/`Model` (Cohu 3950/3965, Bosch AUTODOME, Axis PTZ domes); both are carried on the source (and served by `/api/cctv/sources`) as `model` and `manufacturer` for identified-hardware consumers (vendor-generic strings such as `PTZ` name no model and are omitted). Frames are fetched at request time and never stored or redistributed. Disable with `CCTV_KINGCOUNTY_ENABLED=0`.
 - **WSDOT highway cameras.** Keyless. The camera list is the Esri JSON layer `data.wsdot.wa.gov/travelcenter/Cameras.json` — the same layer WSDOT's own Travel Center map consumes (~1,700 point features, EPSG:3857 geometry converted to WGS84 on load; the body carries Windows-1252 bytes and is decoded as such). Only frames on WSDOT's own `images.wsdot.wa.gov` host are registered — the catalog also lists ~70 partner cameras (Oregon DOT, City of Seattle, lodges, airports) whose own terms apply, and those are skipped rather than proxied. WSDOT's layer metadata marks the feed for "low volume" use (see WSDOT's [travel information disclaimer](https://wsdot.wa.gov/about/policies/travel-information-disclaimer)). The catalog is fetched once per CCTV catalog refresh (every 15 minutes), and a camera's frame is fetched only when that camera is viewed; frames are never stored or redistributed. The live feed's `CompassDirection` is a single cardinal (N/E/S/W), `B` (both directions — most rows), `O`, or null. A single cardinal gives a high-confidence heading (the diagonals NE/SE/SW/NW are mapped too should they appear); `B`, `O`, null, and any other code carry no single facing and use the shared id-hash fallback at low confidence. By default the 250 cameras nearest Seattle and Spokane load; `CCTV_WSDOT_MAX_SOURCES` changes the cap (8–1,200) and `CCTV_WSDOT_ENABLED=0` turns the pack off. A keyed WSDOT Traveler Information API serves the same population for higher-volume use and is deliberately not required here.
+- **Hong Kong Transport Department traffic snapshot cameras.** Keyless. The English camera list is the public DATA.GOV.HK XML at `static.data.gov.hk/td/traffic-snapshot-images/code/Traffic_Camera_Locations_En.xml`; frames are stills on `tdcctv.data.one.gov.hk`, and only that host is registered. Frame URLs are rebuilt from each camera key (`https://tdcctv.data.one.gov.hk/{KEY}.JPG`) rather than taken verbatim from the catalog. Stills were probed to answer directly on that origin with no redirect hop. Frames are fetched at request time and never stored or redistributed. The dataset publishes no camera facing, so headings use the shared id-hash fallback at low confidence and are corrected with the in-app calibration gizmo. By default nearly the full catalog loads (~1,013; pack cap 1,100), prioritized nearest Central, Tsim Sha Tsui, Sha Tin, Tsuen Wan, Tai Po, Fanling, Tuen Mun, Yuen Long and Tseung Kwan O so a lowered cap still spans Hong Kong Island, Kowloon and the New Territories. When the sum of packs exceeds the catalog-wide ceiling, shared round-robin keeps every lane represented. `CCTV_HK_MAX_SOURCES` (8–1200) changes the cap and `CCTV_HK_ENABLED=0` turns the pack off. The DATA.GOV.HK Terms of Use require attribution to the Government / Transport Department / DATA.GOV.HK.
 - **Statens vegvesen road cameras.** Keyless. The camera list is one GeoJSON request to the OGC API Features view of the official DATEX 3.1 CCTV site table (`ogckart-sn1.atlas.vegvesen.no/ogc/features/v1/collections/datex_3_1:CctvSimple/items`), so no DATEX account is needed; frames are stills on `kamera.atlas.vegvesen.no/api/images/<cameraId>`, and only that exact path per camera is registered. Cameras the feed reports as faulty are dropped. About 135 working cameras also publish live HLS (`kamera.vegvesen.no/public/<cameraId>/manifest.m3u8`, MPEG-TS); those play as live video through the bounded in-memory HLS relay, with the still as the snapshot fallback, and only that exact manifest path per camera is registered. `CCTV_VEGVESEN_VIDEO=0` keeps every camera on stills. `orientationDescription` names the place a camera faces, not a bearing, so it goes into the label and headings use the id-hash fallback at low confidence. By default every live camera loads (~850); `CCTV_VEGVESEN_MAX_SOURCES` (8–1000) lowers the cap, keeping the cameras nearest Oslo, Bergen, Stavanger, Trondheim, Kristiansand, Bodø and Tromsø and `CCTV_VEGVESEN_ENABLED=0` turns the pack off. Frames are fetched at request time and never stored or redistributed. The NLOD attribution is registered in the Data attribution popover.
 - **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.

 - **No verbatim client headers upstream.** The CCTV media route is the one route that relays a request header (`Range`, for video seeking). It is parsed and canonicalized before it is forwarded: one `bytes=` range only, with every accepted form — explicit span, open-ended and suffix — bounded to the same 64 MiB ceiling the relay applies to a declared response body. Multi-range, malformed, inverted and non-`bytes` values are dropped and the request proceeds without a `Range`, as RFC 7233 §3.1 prescribes. Bounding the request bounds what is asked for: a response that declares no length — live streamed media, or a chunked body from an upstream that ignores the `Range` — has no ceiling. An upstream request the browser has stopped waiting for is cancelled rather than left running, whether the viewer leaves before the headers arrive or during the body.
 - **Transit fetches registered feeds only.** `/api/transit/vehicles/<id>` resolves the id against `src/data/transitFeeds.js`; the browser never supplies a URL, and a feed that is registered but disabled does not resolve at all. Redirects are followed manually and each hop is validated against the feed's own https origin before it is requested, so an off-origin or downgraded hop is refused rather than contacted. Bodies are capped at 8 MB, the protobuf is decoded server-side under entity-count and string-length ceilings, a differential feed is refused, and snapshots live 15 s in memory with no disk cache. A per-feed admission limiter and a failure cooldown ladder bound what this process can ask of any operator.
 - **Local receiver feeds are operator-configured and local-only.** `/api/local-receivers/aircraft` reads only the `aircraft.json` URLs in the server's `LOCAL_RECEIVER_FEEDS`; the browser never supplies an address. Each host must pass the shared tap address rule (`src/data/tapAddress.js`: loopback, RFC1918, `localhost`, `*.local`; no link-local, IPv6 or other names), the scheme must be http(s), the path must end in `aircraft.json`, and credentials, queries and fragments are refused. Invalid entries are logged at startup and never fetched. Reads use a 2 s timeout, refuse redirects, cap bodies at 2 MB and share one read per second; responses name each feed by band only and never carry upstream error text.
+- **Validated response formats.** Proxied bodies are relayed only in the format the route serves. CCTV frames and the Street View fallback accept JPEG, PNG, GIF, WebP and AVIF only, sent under their canonical type; any other type falls through to the next fallback. Live CCTV media must match its feed kind (`video/mp4`, `video/webm`, or `multipart/x-mixed-replace` with a boundary) before it is relayed or the camera counts as healthy, and its redirects stay on the registered origin. GBFS bodies must parse as JSON and are re-serialized as `application/json; charset=utf-8`. Camera catalog URLs are pinned by parsed URL — scheme, exact host, no credentials, default port, and a normalized path inside the agency's image directory — and a redirect on a pinned host must stay inside the same directory. Every `/api/cctv` route uses the keyless cross-site checks described below, so cameras stay reachable behind a reverse proxy; a request carrying forwarding headers never reaches the key-bearing Street View fallback and gets the placeholder frame instead, as when no key is configured.
+- **Consistent API response headers.** Every `/api` response, including errors, partial content, Host refusals and unknown routes, carries `Content-Security-Policy: default-src 'none'; sandbox` and `X-Content-Type-Options: nosniff` (`apiResponseHeadersPlugin` in `build/vite.js`, installed ahead of the Host check). A route that sets its own policy adds it as a further policy; it never replaces this one.
 - **Response-size caps and timeouts** on proxied responses.
 - **Sanitized errors** — internal error details are not echoed back to clients.
 - **Coalesced OAuth refresh** and cached successful responses only (OpenSky).
 - **Redacted debug logging.** The voice debug log (`.gev-logs/`, gitignored) strips API keys, bearer tokens, client secrets, and image data URLs before writing.
-- **Cross-site gate on cost/log endpoints.** The cost-bearing (`/api/realtime/token`, `/api/openai/hud-summary`, `/api/google/nearby-places`, `/api/google/text-search`), quota-bearing (`/api/mapillary/*`, with a per-IP limit on tiles, and `/api/tomtom/*`, backed by its persistent daily tile budget) and log (`/api/realtime/debug-log`) endpoints refuse cross-site browser requests: a foreign or opaque `Origin`, a `Sec-Fetch-Site` other than `same-origin`/`none` (this is what blocks an `<img>`/navigation that carries no `Origin`), or any reverse-proxy/CDN forwarding header returns `403`. Non-browser loopback tools (the repo QA harnesses POST the token endpoint with no `Origin`) and the explicit `HOST=0.0.0.0` LAN opt-in keep working — the gate deliberately does not require a loopback remote address; that stricter requirement belongs only to the credential panel (`admitKeySetupRequest`). The Host check (`allowedHosts`, applied by `hostCheckPlugin` ahead of every route, since Vite's own check runs only after plugin middleware) rejects a rebinding `Host` before any handler runs, in every mode, and the gate is defense in depth behind it: the LAN opt-in keeps that check and accepts only IP addresses, `localhost` and names listed in `GEV_ALLOWED_HOSTS`. **Limit:** a name you list there is trusted like the app's own address, so list only names you control. The keyless terrain route (`/api/terrain/heights`) uses the same cross-site checks, minus the forwarding-header refusal: it guards only the per-client quota and point cache, not a key or a bill, and the map needs it to render behind a reverse proxy.

 Allowing `maps.googleapis.com` in `script-src` also trusts its JSONP endpoints, which can bypass the script allowlist if an HTML-injection bug exists; this is an accepted limitation of loading the Maps JavaScript API, alongside the existing `'unsafe-eval'` allowance.

+## Ordinary status badges

+CCTV source/frame labels, calibration provenance and Weather coverage labels use

+replace nodes. Empty coverage remains hidden.
+
+Feature owners retain the status rules, machine-state attributes, translations
+and announcement policy. CCTV frame acquisition (`idle/loading/error/ready`)
+remains separate from provider status: retained pixels do not imply a healthy
+feed. Calibration still distinguishes manually saved, catalog-curated and raw
+prior poses; unsaved edits override the label until save/reset. Coverage labels
+remain geographic scope, not health claims. Existing colors and the source
+badge's polite live region are preserved; coverage and calibration do not gain
+live regions. Interactive layer toggles, progress indicators and world overlays

+## Ordinary action buttons

+Scene panel actions, shot LOAD/DEL actions, the EDIT DETAILS / SHARE SCENE
+bar and one-shot CCTV actions use `ui/actionButton.js` and the shared
+`gev-action-button` surface in `ui/styles/action-button.css`. Static templates
+apply the same classes as generated buttons. The native builder accepts translated
+text, default/danger variants, default/compact sizes and disabled/accessibility
+properties; it installs no listeners and owns no application state. Feature
+controllers retain callbacks, enable/disable rules, confirmation prompts,
+persistence and teardown. The smaller shot actions retain their existing sizing
+and hover treatment. Feature CSS still owns panel layout and translated wrapping.
+
+CCTV enable, coverage, auto-hop, projection and adjustment toggles, editable
+calibration-value chips and the scene authoring dialogs retain their specialized
+controls. Existing `scene-btn` hooks remain compatible with Street Level and

+## Segmented selectors

+Segmented selectors use the controlled DOM adapter in `ui/segmentedControl.js`
+and the shared `gev-segmented` / `gev-segment` surface. Model coverage, label
+allocation, drawing shape, Street View fit/panorama filters and imagery mode keep
+their feature-owned values, actions and persistence. Painting a restored value
+does not emit a change or move focus. Existing keyboard policies remain explicit:
+Street View uses arrows/Home/End with one tab stop, imagery mode uses arrows from
+its controlled selection, and Display keeps its existing native button behavior.
+Pure value navigation is separate from DOM rendering for reuse by a future view.
+Segments keep their word minimum width: compact inline groups such as FIT/FILL
+and ALL/360°/FLAT must not break short labels mid-word. Collapsed Weather follows
+the same exclusive-rail hiding rule as the other readouts.

+
+## Style
+
+- Mainland usage and Simplified characters. Address the user neutrally, without 您/你 where a plain imperative works: 「点击地图」, 「重试」.
+- Chinese has no case: an UPPERCASE English HUD label becomes the same short Chinese label. Keep labels as short as the English: 「实时」, 「过期」, 「关」.
+- Full-width punctuation in Chinese text: ，。：；？！（）“”. A dash is 「——」 without spaces; keep `·` as the HUD separator and `…` for ellipsis.
+- One space between Chinese and Latin letters or digits: 「AIS 船舶」, 「24 小时」, 「{count} 个」. No space next to full-width punctuation.
+- Units: km, m, km/h, m/s, kn, ft, MW, °, % stay as written; time words are 小时, 分钟, 秒 after a number (「5 分钟前」).
+- Product names, provider names and codes stay as they are: Google, Cesium, CelesTrak, NOAA, FIRMS, AIS, ADS-B, GNSS, CCTV, HUD, CRT, NVG, FLIR, WHOT/BHOT, Ironbow, CONUS.
+
+## Plurals
+
+`Intl.PluralRules('zh-CN')` has one category, `other`: a `tn()` entry has only that form. Use a measure word next to the number where Chinese needs one: 「{count} 个密钥」, 「{count} 架飞机」, 「{count} 艘船」.

+
+**Build:** `node scripts/build-bright-stars.mjs [catalog.gz]`. Drops the 14
+records without a J2000 position; rounds RA/Dec to 0.001° and magnitudes to
+0.01.

+**Changes made** (CC BY 4.0 asks for them): resampled to 4096×2048; stars
+removed; two images of Jupiter painted over; blurred (0.4°, 2° in the faint
+glow); reprojected to ICRF cube faces; black level at the median sky; saved as
+WebP. Build: `node scripts/build-milky-way.mjs <eso0932a.tif>`.
+
+The panorama's stars sit up to ~2° off; that is invisible in the blurred glow,
+and every sharp star comes from the catalogue.
+
+NASA SVS "Deep Star Maps 2020" was not used: it derives from Gaia DR2, which
+ESA licenses CC BY-NC 3.0 IGO.
+
+## Frame
+
+Both layers are in ICRF/J2000. The cube faces use the WebGL face layout, +X
