SurfAudio

SURF VOID's sound, driven entirely by game.rules events and Rules.state. Lives on the scene's game entity; the AudioListener is on the player camera. In play it spawns one temporary child root SurfAudio_root with a non-spatial Audio source per voice (despawned on destroy, never saved).

Voices (clips under /zero/source/game/audio/)

• music_title (music_title.soundClip, 45 s calm synthwave) — audible while phase == "title".
• music_run (music_run.soundClip, 60 s driving synthwave) — audible in ready/running/finished; ducked under the finish fanfare.
• wind (wind_loop.soundClip) — air-rush loop; volume and pitch rise with Rules.state.speedU (full at windFullSpeed).
• hiss (surf_hiss.soundClip) — surf-slide loop, plays while Rules.state.surfing, stops when it clears.
• One-shots: jump, land (volume/pitch scaled by land(impactU)), checkpoint (pitch steps up per CP), respawn (also on restart), finish, click (on begin = Enter on the title, softer on start).

Public fields

• masterMusic, titleMusic — music deck levels (0..1).
• windMax, windFullSpeed — wind level at full speed and the u/s that reaches it.
