Planets, belts, wells, loot, mines, stations, the chunk reticle and the flow
clock are evaluated through DrawAhead (Time, Orbit, Height, Position) at one
drawn time; the rail law lives once in Zone.Offset; OrbitPositionAt, GetHeight,
ChunkPose, EvaluateBelt and RideHeight take a time. Fixes the planet jumping
against a co-moving ship at display rates above the step rate.
Not yet built or run (Unity presenter files are verified by compile only on
Starfire).

MineInstance reads a Mine and draws it (latest sim body at the grid height, spin, real-time pulse by arming and
trigger); ZoneRenderer makes one per Zone.Mines add and plays the blast on remove; EntityInstance gives a mine
layer no effect manager. AetherDb mine-launcher authors the item; the catalog, prefab and scene wiring follow in
later commits, so this one does not build a playable mine (no MinePrefab yet).
