Effects are driven only by existing telemetry (speed, slip angle, lateral grip, completed task count). They do not feed back into physics, policy inference, rewards or observations. Visual RNG is separate from simulation RNG.

2026-09-07 playback revision: cheers are dispatched per completed task (no drift
trigger or 8-second cooldown), queued sequentially for rapid completions. Music
loops over the full decoded track, with explicit loop bounds, normalized resume
position and ended-source recovery. Source audio files are unchanged.

2026-09-07 collection revision: coin-gold.png is the original stk-media/models/gold.png texture. See COIN-LICENSE.txt. The coin mesh, shrinking, pop, spin and HUD flight animations are newly implemented in Three.js. Cheers now fire at the coin pop; score increments on arrival at the HUD.

2026-09-07 audio revision: long-form music now plays through an independent HTML media element with native looping, ended fallback and stalled-playback recovery. Short Web Audio effects remain separate, with bounded parameter automation and low-pass filtering for the skid loop. Original sound files are unchanged.
