identity_music_beds_generate
Generate identity music bed
App-only Brand/Music Studio generation. Composes a real instrumental music bed with a music model (Lyria 3 Pro by default, or Eleven Music) and materializes it as an account-owned IdentityMusicBed row, with the current project as origin when project_id is given (omit it to bake at the account level from Music Studio). The prompt describes the musical character (genre, instruments, mood, BPM); bed doctrine (instrumental, speech-friendly, loopable) is applied server-side. If provider/storage is unavailable, returns blockers without creating a browser-only library fork.
