Five fixes: video-in-sky, streaming metadata, 3D settings z-index, vapor in access, MIDI-only downloads

VIDEO IN THE SKY — project the found-video layer onto a big yaw-billboard screen high in the night sky behind the 3D band. Uses VideoLayer._frontEl() as a THREE.VideoTexture, LOCAL clips only (_frontKind === "local")

STREAMING METADATA — MediaSession now reports artist "stellate.app", album = the PARENT (dominant) genre, song/title = the CURRENT CLOSEST genre (S.best, the verifier's nearest, which drifts as you travel).

SETTINGS IN 3D MODE — the star-cruise canvas (z40) / VHS overlay (z44) / HUD (z55) sat above the settings + about modals (z7), so opening the gear in aliens view popped the panel behind the flight.

VAPOR IN THE ACCESSIBLE VIEW — add the live-only mall-haze master-EQ slider to access.html (parity with the map); wired via setVapor, persisted, aria-valuetext.

Verified: full-boot, starcruise-run + nav, access-ui 12/12.
