React Three Fiber entry point: <Fleet> (instanced traffic, trains, boats, aircraft, rockets) and
<Vehicle> (one vehicle), plus everything from threejs-vehicles (the classes are re-exported as
FleetImpl and VehicleImpl). Props are the classes' JSON settings; every render calls reset(props)
(rebuilding only when groups or seed change), and update() runs in useFrame.
