Sound for the experience, plus the design to control it.
Soundtrack layer (ambience), all license-clean (PD/CC0), recorded in
docs/audio-candidate-pool.md (media gitignored; re-sourceable):
- cosmos: Pillars of Creation sonification (NASA, PD)
- orbit: station room-tone hum (CC0)
- coast: sea waves + terns (CC0)
- reef: 6-layer NOAA soundscape + CC0 submerged bed (PD + CC0)
- abyss: blue-whale moan (NOAA, PD)
Solution Design (proposed): split the bundled Content selector into two
orthogonal dials, Visual (on/off) x Audio (off/soundtrack/white-noise),
unlocking white-noise+video. Soundtrack follows the single Altitude dial;
white noise is altitude-independent. Reframes the networked-control-surface
spec SS3/SS5 (still proposed/unbuilt -> clean pre-impl edit). Music layer deferred.
Dev panel: links to the clip + audio review galleries; sticky stage/panel layout.
gitignore: audio media, review_audio.html, .DS_Store.
