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.

The JSON blocks below are the exact MCP descriptor projections served by Rails for the named profiles at capture time. Security schemes and resource URIs may vary by connected host.
