 - **Secrets stay server-side.** Anything needing a private key goes through a local proxy under `server/providers/`. The browser only ever sees the Google Maps key (which you restrict) and ephemeral tokens.

 - **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.

 - **Full Content-Security-Policy.** The dev and preview servers send a real CSP (`script-src 'self' 'unsafe-eval' blob:` plus the YouTube, Facebook and X scripts the Nepal event's embedded media loads and the Maps JavaScript API that Street View runs on, with a matching `frame-src` for their players and posts: no inline script and no other script origin; `blob:` covers the object URLs Cesium's bundled workers bootstrap through in the built app), alongside the existing `X-Frame-Options: DENY` and `frame-ancestors 'none'`. `'unsafe-eval'` stays because Knockout, bundled inside Cesium's widgets package, resolves the global object with `eval` at load time and the globe does not initialize without it; styles permit `'unsafe-inline'` and Google Fonts because Vite's dev client injects `<style>` elements.
 
 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.

+are not moved in the DOM: `styles/mobile-shell.css` presents the rails and dock
+as the sheet, and the dock's Location and Presets trays render inline. The voice
+control floats above the tab bar while no sheet is open.
+
+Sheets borrow panels. Opening one expands its panels without persisting them or

 - **Grounded 3D handoff is terrain-validity gated (2026-08-23).** A ready civilian or military glTF does not own the visual until `groundSnap` (`src/data/groundSnap.js`) can answer with a MEASURED photoreal-surface height. On success the layer writes `height + the model's measured belly offset` before revealing the model. Cache movement is measured on the WGS84 surface, not across altitude, so a stationary contact keeps its snap through poll-time vertical-datum changes. Model existence or GPU readiness alone never suppresses the billboard floor, and ordinary zoom/style/deselect transitions preserve a valid snap cache. **Two states, and the difference is the whole design.** COLD — nothing has ever resolved for this icao (tiles still streaming on first sight, sample failure, backoff after a first miss): there is no evidence of where the ground is, `heightFor` returns null, the model stays hidden and the depth-test-free 2D billboard remains opaque and floored. WARM — a snap resolved and then a >`MOVE_INVALIDATE_M` (50 m) taxi move stopped it answering directly: the measurement is DEMOTED to a bounded last-known rather than deleted, and it keeps answering while the resample is outstanding, so a taxiing aircraft does not pop 3D→2D→3D across a 2–30 s retry backoff. The bound is `HELD_SNAP_MAX_DRIFT_M` = 250 m from the spot the value was measured at, past which the hold is dropped rather than stretched and the contact is COLD again. It is spatial with no timer beside it (ground under a contact that has not moved does not change; what invalidates the value is the contact MOVING) and deliberately a quarter of the billboard chain's `HELD_FLOOR_MAX_DRIFT_KM` — that hold only ever RAISES a sprite, while a held snap IS the model's placement, so its error shows in both directions. A fresh sample releases the hold, and so does a ground flip (which already calls `forget`). **A loading model is HIDDEN, never zero-scaled:** admission sets `show = false` (Cesium's default is `true`, and an unplaced primitive would claim the visual at the identity matrix), and ownership is `ready && show` — Cesium 1.138's `Model.update` has no `show` guard, so hiding a primitive costs its load nothing.
 - Commercial and military aircraft use the same high-level FLEET model regime: 2D billboards when zoomed out, optional glTF models when closer, controlled by the DISPLAY rail `3D` toggle and `Proximity` / `All` modes. Since 2026-08-16 (Hangar fleet) models are PER-CLASS: real CC-BY GLBs for light/bizjet/turboprop/widebody/helicopter/uav (`CLASS_MODEL_REAL` in `src/data/aircraftClass.js` — meters-baked, scale 1, per-model belly/radius; provenance in `public/models/README.md`), the shared `airplane.glb` for the remaining civilian classes, and the military layer maps weight classes (real GLBs / 747 heavies / `jet.glb` fastjets, per-model heading offsets, flat amber or emergency red). Textured civilians carry a HEAVY tint, not a light one: `MODEL_COLOR_BLEND_AMOUNT` is `0.94` in BOTH layers under Cesium's `ColorBlendMode.MIX`, so the class colour supplies 94% of the surface and the asset's own texture ~6%. The visual direction is clean light silhouettes with only a weak diffuse contribution from the approved textures, so liveries deliberately do NOT read. IR boost raises the blend to a full `1.0`. Under NVG/FLIR (map preset or Cockpit vision) models render unlit flat-white at full alpha and scene fog is disabled (fog otherwise blacks out distant models with the globe hidden); state restores on exit.
 - The DISPLAY-rail `3D` toggle is the user-facing activation path for both aircraft layers. Their small approved GLBs build their render resources without Cesium's frame-spread job queue, preventing continuous Photorealistic 3D Tiles streaming from starving model readiness; model caps, tracking, camera, and fallback billboards are unchanged.
-- **The `3D` toggle DEFAULTS ON in `proximity` on a first run.** Proximity is itself the budget — models appear only below `MODEL_ALT_CEIL_M` and only for the nearest `MODEL_MAX` in view — so the default costs nothing at globe scale, and `all` remains a deliberate opt-in. A fresh boot runs NO layer-state restoration (`LayerStateCoordinator.start()` returns early with neither a share payload nor stored state), so four independent initializers decide what a first-run operator sees and must agree: `booleanOption('models3d', 'e', true)` in `src/data/layerState.js`, `_models3dEnabled = true` in BOTH flight layers, `this._models3dEnabled = true` in `src/ui.js`, and the `active` / `visible` classes on `#models3d-toggle` / `#models3d-mode-row` in `index.html`. All four are pinned together in `src/data/layerState.test.mjs`. Explicit state still wins: because the codec omits default-valued options, `models3d: false` is now what travels in a link (`lo=…f.e.0`) and restores OFF at both aircraft layers. **Consequence for returning users:** a stored `gev:layer-state:v2` blob is a FULL options snapshot, so a session that wrote one before this change carries `models3d:false` and keeps 3D off until the operator flips it (or clears the key) — the durable snapshot is treated as the recipient's own state, by design.

+## 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」.
