// LIGHTCYCLE ARENA — the tron mood: a dark fine-grid floor, edge-lit black
|
|
// towers, and ten light-cycle trail walls sweeping the street lattice IN
|
|
// TEMPO. Each trail's front is a pure function of the beat (one lap per
|
|
// `trail_beats`, per-trail phase offsets so the arena never syncs into one
|
|
// pulse), the head burns white and the wall ages behind it. Pattern
|
|
// taught: `trails` is the tron ingredient — walls collapse ahead of their
|
|
// front in the vertex shader, so the sweep costs nothing on the CPU.
