Draw transit vehicles as trolleybuses, cable cars, funiculars, gondolas and monorails

The transit layer knew five modes, so a trolleybus drew as a bus, a
funicular as a train and a coach as a city bus. The GTFS basic route types
are now modes of their own (trolleybus, cable_tram, monorail, funicular,
aerial_lift), each with an icon, colour, detection tier, card word, voice
name, speed ceiling and fleet model.

A vehicle record may carry its route's GTFS route_type as routeType. It
settles the mode after the feed's fleet hint and before its route hint, and
picks the finer model (a coach for 200, a high-speed set for 101) when the
type is a kind of the vehicle's mode. Retained history classifies epochs
through transitModeFor too, so trails join the live vehicle.

Route hints from each operator's routes.txt: Prague's trolleybus lines
(51-59, 232, 275) and Petrin funicular, and the trams, trolleybuses and
metro lines of Bucharest, Cluj-Napoca and Turin. A feed may also name
route corrections that outrank the route type: Le Havre's routes.txt types
its funicular (8-FUNI) as a bus, so it is corrected to a funicular.

 - 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. Every model is one of the project's procedural fleet models (`public/models/fleet/`, MIT, 122 GLBs, about 2 MB in all; `public/models/README.md`), chosen per aircraft by `aircraftModelSpec` (`src/data/fleetModels.js`): the first of its ICAO type's callsign rules in `types.json` (`aircraft_callsign`) its callsign matches, else its type's entry, else the model of its `classifyAircraft` class for a type the map lacks, else its ADS-B emitter category's, else the default airliner. It is drawn LIFE SIZE: the type's published length over the model's built length (`src/layers/flights/modelSpec.js`, shared by Flights, Military Flights and Local ADS-B), and a grounded aircraft stands the model's scaled clearance above the ground. An airport ground vehicle (feed type `ZVEH`) is a fire truck (`FIRE…`), pushback tug (`PUSH…`, `TUG…`), van (`DEICER…`, `SQUID…`, `SQB…`) or else a car by its callsign, and a ground station (`GRND`) is an 11.8 m radio mast; these models (catalog category `other`) are drawn at their built size, and such a contact with no altitude stands on the ground instead of at the airborne default (`src/layers/flights/records.js`). `classifyAircraft` still picks the 2D icons. The whole set loads once, up front, when a layer that draws it starts (`loadFleetModelSet`, which logs `[Fleet] N/122 models (X MB) loaded in N ms`); models are built from those bytes, never fetched mid-session, and an aircraft stays its billboard until the set has loaded. Every aircraft model draws its mesh's own colours (`aircraftModelBlend`, `src/data/aircraftModelLighting.js`): Cesium's `ColorBlendMode.HIGHLIGHT` with white, in Flights, Military Flights and Local ADS-B alike; the tracked colour (cyan, or amber in Military Flights) and the emergency red multiply into the mesh, so its paint still shows. IR boost draws them flat white (`MIX` at `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.
-- Vessels, Transit and Rail draw fleet models under the same DISPLAY rail `3D` toggle, at the same altitude ceiling, caps and add/keep radii as the aircraft (`FLEET_MODEL_POLICY`, `src/layers/flights/policy.js`; `createFleetModelLayer`, `src/data/fleetModelInstances.js`). A vessel's model follows its AIS ship type and is drawn at its reported length and beam (AIS static dimensions A+B and C+D, now carried on vessel rows as `length` and `beam`), standing at the sea surface, heading by true heading then course. An aid to navigation is not a hull: a vessel record whose type names a buoy, beacon, mark, RACON or light, or whose MMSI is an aid-to-navigation station's (`99MIDxxxx`), is `isAidToNavigation` (`src/data/vesselTypes.js`) and is drawn as the set's `buoys` model of the IALA mark its type names (`aidToNavigationModel`, `src/data/fleetModels.js`: cardinal N/E/S/W, port or starboard hand, preferred channel by its side, safe water, isolated danger, special mark; a beacon, light, light vessel, RACON or reference point with no mark of its own is the special mark), else a red can (`DEFAULT_AID_MODEL`), at its built size and facing north whatever heading it reports. A type is an aid's when it is one of the 32 kinds an aid report names or uses a word for one (buoy, beacon, cardinal, safe water, RACON, lighthouse and so on); a vessel that works on aids (`Buoy Tender`, `Buoy Layer`) is not one. Its icon is a bone-white ringed disc (`AID_TO_NAVIGATION_STYLE`, `src/data/vesselLabels.js`) instead of a chevron, never rotated, and its card, selected card and HUD readout (`src/layers/vessels/cards.js`) show its kind alone, whole, in that colour: no speed or heading, since a fixed mark has neither. AISStream subscribes to `AidsToNavigationReport` (message 21) by default, and the server names each report's aid type code (0 to 31) as its kind (`aidToNavigationTypeName`: `20` is `Cardinal Mark N`) rather than reading it as a ship type, and its name runs on into the report's `NameExtension`. A virtual aid (the report's `VirtualAtoN` flag: a mark broadcast where nothing physical stands) carries `virtual: true` on its row, and on its vessel source record (the live-source contract's `virtual`, `src/sources/live/contract.js`, false unless a source says true; any source may set it). It keeps its disc but never gets a model (`vesselModelSpec` returns null for it, and the vessel layer gathers no model item for it), and its card and readout add `VIRTUAL` after its kind. `aisStreamRows` (`server/providers/vessels/ais-store.js`) puts every vessel ahead of every aid, so a capped request (the layer asks for 12,000 rows) never gives up a ship for a buoy. The `vessels_in_area` tool (and the brief built on it) counts ships only: it leaves aids out of its rows, counts, breakdowns and speed stats. A transit vehicle's model follows its layer mode (bus, tram, subway, rail or ferry; a vehicle of `unknown` mode keeps its icon), a train's its rail category and mode (rail, metro or tram). Neither the transit nor the rail sources carry a GTFS `route_type` or a finer mode (monorail, gondola, funicular, cable car), so the set's models for those and their `transit.elevation` lifts are not reached by any live source today. Both stand on the road or rail top they are drawn on, without the 1.5 m `GROUND_FLOOR_LIFT_M` their icons carry, and are painted in their mode or category colour where the model's `_TINT` attribute marks it. A vessel model is clipped at its waterline (one clipping plane per model, at the model origin's horizontal plane), so its hull below the water never shows through a plain globe, which Cesium does not depth-test models against. Under the NVG/FLIR styles (the Flights `irBoost` parameter) these models render unlit flat white, as aircraft models do. Each vehicle's icon stays the visual until its model is loaded, ready and placed; a model is picked as its icon is, and a vehicle drawn as its model keeps its selection card and its place in the detection overlay.

A transit vehicle's model follows its route's GTFS `route_type` when its record carries one and that type is a kind of the vehicle's mode (`types.json` `transit.route_types`: 200 a coach, 101 a high-speed set, 106 a regional DMU, 710 a double-decker), else its layer mode (`transit.modes`: bus, trolleybus, tram, cable car, subway, monorail, rail, funicular, gondola or ferry; a vehicle of `unknown` mode keeps its icon); a fleet hint that overrules the route (a bus on a tram route) leaves the type unused. A monorail and a gondola are raised by their `transit.elevation` lifts. A train's model follows its rail category and mode (rail, metro or tram). The bundled GTFS-Realtime proxy carries no route type, so its vehicles draw their mode's model; a source that adds `routeType` reaches the finer ones. Both stand on the road or rail top they are drawn on, without the 1.5 m `GROUND_FLOOR_LIFT_M` their icons carry, and are painted in their mode or category colour where the model's `_TINT` attribute marks it. A vessel model is clipped at its waterline (one clipping plane per model, at the model origin's horizontal plane), so its hull below the water never shows through a plain globe, which Cesium does not depth-test models against. Under the NVG/FLIR styles (the Flights `irBoost` parameter) these models render unlit flat white, as aircraft models do. Each vehicle's icon stays the visual until its model is loaded, ready and placed; a model is picked as its icon is, and a vehicle drawn as its model keeps its selection card and its place in the detection overlay.
 - **Aircraft models skip Cesium's dynamic environment map (2026-10-24).** Flights, Military Flights and Local ADS-B pass `environmentMapOptions: AIRCRAFT_ENVIRONMENT_MAP_OPTIONS` (`{ enabled: false }`, `src/data/aircraftModelLighting.js`) to every drawn model. Otherwise each `Model` renders the sky around it and reads it back from the GPU (`readPixels`) when it is first placed, and again whenever it moves more than 1 km, the scene's atmosphere settings change, or (under sunlight dynamic lighting) an hour of scene time passes (`DynamicEnvironmentMapManager`, Cesium 1.138). The models are lit from Cesium's default spherical harmonics instead, with no specular environment map, so the sky's model-lighting cube map no longer reaches aircraft. `src/data/aircraftModelLighting.test.mjs` pins the option at every drawn model call; every model is built from the fleet set loaded up front, so there is no separate preload.
 - 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/aircraftDisplay.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.
