Street level view/cameraFollow/groundClick/index, traffic footprint/viewport/ingestion, transit viewport/trails/state/rendering, FIRMS state/viewport, installations controls/viewport/state, radio queries/navigation/state, bikeshare viewport, submarine cable overlay and data/detection now use src/geo for Math, Cartesian2/3, Cartographic and WGS84 maths. Cesium stays for Rectangle, Ray, BoundingSphere, HeadingPitchRange, EasingFunction, EllipsoidGeodesic, EllipsoidalOccluder and the Ellipsoids passed into Cesium (pickEllipsoid, occluders). traffic/state.js keeps its Cesium lerp scratch (written per frame by Cesium.Cartesian3.lerp in animation.js; a geo scratch cost +4-7% there) and traffic/timing.js stays on Cesium (a test keeps it source-equivalent to model.parseRoads, outside this batch). street-level-layer, traffic-layer, installations-layer, bikeshare-layer and submarine-cables own the src/geo files.
Traffic roads come from OpenFreeMap vector tiles, or TomTom flow tiles with a
key (Hybrid by default). Military areas use OpenFreeMap polygons with a bundled
worldwide name index; wide views show named points. ALPR reads an hourly
OpenStreetMap extract. Cockpit place context and country, state and US county
outlines use bundled Natural Earth and US Census data. Overpass is used only
when an operator configures their own endpoint.
Also: camera arrivals no longer land below ground, keyless terrain retries on
429, bounded relation geometry for configured Overpass, one shared
OpenStreetMap credit, and separate tile and API transports for embedders.

Street Traffic draws on OpenStreetMap for geometry and TomTom for flow,
and the row said "Road data temporarily unavailable" whichever one
failed. The reporter of #661 went and verified a TomTom key while every
public Overpass mirror was refusing their network with HTTP 406 — a
status fetchRoads already had and dropped on the floor.
Classify the refusal where the layer talks to Overpass: 429 is
"Overpass rate-limited", 504 is "Overpass timed out", anything else is
"Overpass refused the road query (HTTP <status>)". The first two are the
words alpr's Overpass source already uses; the status is what says which
upstream declined, which a single-source layer never has to.
The error carries its status as a RoadRequestError, following
LiveSourceError in src/sources/live/contract.js, so a caller can branch
on the code without parsing English. The catch promotes a classified
refusal and keeps the general line for everything else — the branch is
on the error type, not on its text, because a dropped socket throws
whatever the platform felt like saying and "Failed to fetch" on a panel
row helps nobody.
Retries, backoff, caching and the mirror rotation are untouched.
