Replace the single ethereal loop with the operator's chosen set — Music for Manatees, Dewdrop Fantasy, Eastminster, Overheat, Concentration (Kevin MacLeod, CC BY 4.0, drumless). The Music source now plays one track and every 5 min crossfades to a random OTHER track (pure HEFScrub.pickNextIndex, never an immediate repeat), altitude-independent, reusing the two audio elements; both primed in-gesture for Safari. Intervals injectable via window.__hefMusicRotateMs / __hefMusicXfadeMs. Media loudness-normalized + transcoded under the 25MB LFS limit (build_audio_media MUSIC), committed via LFS; ethereal loop retired. CC-BY attribution added to credits.html. Docs updated (music-candidate-pool = final set; audio-candidate-pool ethereal section superseded). +2 node unit (pickNextIndex), +2 e2e (music-playlist), audio-source spec updated. 40 unit + 49 e2e green; live probe confirms playback + rotation.
