 - **Québec CCTV (MTQ / Québec 511, Montréal and scenic links).** `public/quebec-cameras.json` contains 680 MTQ positions from the official georeferenced WFS (CC BY 4.0), 426 Montréal camera locations derived from OSM (ODbL 1.0), and 14 scenic records with per-row provenance and accuracy. The MTQ video is **opt-in** (`CCTV_QUEBEC_VIDEO_ENABLED=1`): the CC BY 4.0 licence covers the camera locations only, and Québec 511's terms for embedding its clips on another site are unconfirmed, so by default MTQ cameras link to the Québec 511 viewer page instead. With the flag set, the 680 MTQ cameras play the operator's five-second MP4 clip directly in the viewer's browser from `www.quebec511.info/Carte/Fenetres/camera.ashx?id=<id>&format=mp4`, only after the viewer presses Play, so Québec 511 sees the viewer's IP address; Québec 511 refreshes those clips every few minutes. A second browser request supplies an approximate map still. The app does not proxy, store, or read video pixels, and no camera images are bundled. The selected-camera credit names both sources: locations MTQ under CC BY 4.0, video Québec 511. Montréal and scenic entries have provider-page links rather than direct frame URLs; their source-page terms apply. The video remains hosted by Québec 511 under its service terms. No API key is required; `CCTV_QUEBEC_ENABLED=0` disables the pack. Confirm Québec 511's terms of use before setting `CCTV_QUEBEC_VIDEO_ENABLED=1` on a public deployment.

 - **Google Maps Platform.** You supply your own API key and are bound by [Google's ToS](https://cloud.google.com/maps-platform/terms). Google Maps Content (tiles, geocodes, places) **may not be cached, stored, rehosted, or committed** — this app only ever uses it live, which is the compliant pattern. The "Google" attribution is displayed on the globe and must stay visible. Restrict your key (see [SECURITY.md](SECURITY.md)).
+- **Sea Marks and Ski Pistes (#10).** Two keyless raster overlay layers under Infrastructure, OpenSeaMap sea marks and OpenSnowMap ski pistes, requested tile by tile as the camera views them, with no prefetch, bulk download or caching on our side (OpenSnowMap forbids bulk tile download without prior agreement). They drape on the globe on the OSM and Bing stacks and on the Google Photorealistic tileset on Google 3D (see `src/maps/imageryHost.js`). OpenRailwayMap and OpenInfraMap, also requested in #10, are not included: OpenRailwayMap's tile server only answers requests whose Referer is its own site, and OpenInfraMap serves vector tiles that need a vector rendering pipeline.
 - **OpenSky Network.** Its license is **non-commercial**, and operational use of the REST API in a live product can require a prior written agreement with OpenSky — even for non-profit/government use. If you deploy this commercially, contact OpenSky for your own terms. The flights layer is a toggle and runs anonymously by default.
 - **adsb.lol flight fallback.** When OpenSky is unavailable and no last-good OpenSky response exists, the server requests a cached, capped 250 nm adsb.lol point snapshot around the current camera subpoint. This is regional observed context, not worldwide completeness; provenance is exposed in the Flights stats/context row. Military ICAOs remain reconciled through the existing dedicated military registry rather than duplicated.

 - **Re:Earth Terrain.** Keyless (no API key). Used two ways: (1) `src/mapStackController.js` swaps in a `Cesium.CesiumTerrainProvider` pointed at Re:Earth's `cesium-mesh/ellipsoid` quantized-mesh endpoint for globe stacks without a Cesium ion token (e.g. OSM), replacing a flat `EllipsoidTerrainProvider`; falls back to the flat provider if the endpoint can't be reached. (2) The server-side `/api/terrain/heights` proxy (disk-cached, serve-stale) resolves per-point ellipsoidal ground height for entity placement. Both are best-effort with a keyless-safe fallback (bundled EGM96 geoid math) if Re:Earth is unreachable.
 - **OSRM on the FOSSGIS routing servers.** Keyless (no API key). Every route is requested by a person: clicking A and B in the Directions layer, or a voice "route from A to B". The server-side `/api/route` proxy sends an identifying `User-Agent`, pins the upstream host, accepts 2-12 coordinates, rejects any leg over 600 km or a total over 2,500 km, caps the buffered response at 8 MB, times the upstream out at 12 s, rate-limits per client, caches each route for 10 minutes, and coalesces identical requests that are in flight at the same time. Turn-by-turn maneuvers are asked for only when a caller wants them (`steps=1`), so the callers that do not read them send the smaller request. The "fix the map" link the policy asks for is in the Data attribution popover beside the OpenStreetMap credit.
 - **Mapped installations.** OpenFreeMap military polygons use a bundled Overture/OSM name index; wide views show named points. Optional operator-configured Overpass and explicit Google Places searches keep their own source paths. Mapped data does not establish current activity or complete coverage.
- **Place search.** Named-place fly-to uses Google Geocoding when a Maps key is configured, then Photon's public instance, then `/api/geocode` (Nominatim search) when neither answers. `/api/geocode` uses the shared Nominatim forward-search queue at no more than one request per second, sends an identifying `User-Agent` and `Referer`, caches answers for five minutes, shares one upstream call between identical searches already in flight, bounds the queue so a burst is refused rather than held, and drops a queued search whose caller has given up. It asks for one result per search and is not used for systematic or bulk queries.
+- **Place search.** Named-place fly-to uses Google Geocoding when a Maps key is configured, then Photon (`PHOTON_URL`; unset uses the public instance, empty disables it), then `/api/geocode` (Nominatim search) when neither answers. `/api/geocode` and the voice outline route `/api/geocode/outline` share one Nominatim queue (`NOMINATIM_URL`; unset, empty and invalid values disable it; an operator must explicitly select an authorized endpoint): one request at a time at least 1.1 s apart, an identifying `User-Agent` and `Referer`, a short queue that refuses a burst, a pause after 429/403/5xx answers (honouring `Retry-After` in full), at most one retry after a network failure, and a per-install daily cap on public-instance requests (`NOMINATIM_DAILY_CAP`, default 50). Processes using the same installation state file hold one lock through the actual fetch invocation and recording the next public start, with the daily slot persisted before invocation; restarts share that count, spacing and any pause. An unfinished dispatch marker fails closed until operator recovery; it is never automatically reclaimed. Public access fails closed if the state file cannot be read, locked, written or semantically validated. This coordination does not span independent installations or state directories and does not establish an application-wide public-service allowance or authorize public use. An operator-selected non-public endpoint is outside the public cap, spacing and durable-state requirement; an upstream cooldown is kept with the endpoint that returned it rather than leaking across operator URLs. Answers are cached on disk (outlines 90 days, places 30 days, no-results 24 hours); failures are not cached. Outlines are looked up only for an explicit ask, after bundled data and any configured Overpass, and only results whose type suits the ask are used. Administrative outline responses expose country/admin-1/admin-2 identity only when the selected Nominatim row has a recognized, unambiguous address type consistent with its own name; numeric rank, ambiguous types, missing fields and contradictory names do not manufacture identity. It is not used for systematic or bulk queries.
+- **Street and building outlines.** Voice street highlights, pointed-at buildings and grounds use the OpenFreeMap vector tiles the traffic layer already loads. Traffic and outlines share one bounded pending fetch/decode owner per immutable XYZ tile; materialized outline geometry is charged to the retained-byte ceiling and capped by coordinate count. Consumer result caches and request lifetimes remain independent, while eviction or explicit teardown cancels queued idle projections and releases their decoded owner. No Overpass request is made unless `OVERPASS_UPSTREAMS` is configured. Named grounds require a returned name matching the selected place, except that an ask whose head noun names a kind of grounds (a school, university or college, hospital, cemetery, stadium or zoo) may use the part of the smallest unnamed tile area of that class that holds the resolved place; a differently named area never answers. Other anonymous landcover polygons cannot establish identity, so unsupported grounds stay unavailable rather than borrowing a nearby POI name.
 - **Cockpit regional briefing.** `/api/regional-brief` rounds aircraft coordinates into 0.1° cache cells, caches results for five minutes, and resolves physical regions from bundled public-domain Natural Earth polygons without reverse-geocoding requests. Google News RSS is queried with the resolved locality/region first; GDELT is used only when that RSS query fails or is empty. Google's published Google News terms restrict that source to personal, noncommercial use, so commercial deployments must disable/replace it or obtain separate permission; GDELT permits commercial dataset use with citation. The Data attribution popover identifies the active headline sources; article links retain publisher attribution. Headlines are location-query matches, not verified incidents, risk rankings, or evidence that a location is safe. Empty, partial, stale, and unavailable source states remain distinct. Open-Meteo supplies current conditions independently of the news source. `WX OFF` disables cockpit weather rendering only; the Local Info briefing still fetches its source-backed weather values and displays the required linked Open-Meteo credit.
 - **Dynamic weather presentation.** While cockpit mode is active, `/api/weather-effects` requests current Open-Meteo observations for the aircraft/camera location, rounds coordinates into 0.1° cache cells, caches results for five minutes, and may retain a stale observation for up to 30 minutes during a transient outage. WMO condition code selects the visual family; observed cloud cover, precipitation, visibility, wind speed, and wind direction bound its strength and motion. Missing or expired weather renders no synthetic atmospheric effect, and normal globe view never renders the weather overlay.
