What it does
- Selects the music prompt based on
--mood. - Calls the Interactions API with the
lyria-3-clip-previewmodel. - Generates a ~30-second music clip.
- Saves as MP3 to
{workspace}/audio/music/background.mp3. - Gracefully handles failures — the pipeline continues without music.
Dependencies

Output
- File:
{workspace}/audio/music/background.mp3 - Format: MP3
- Duration: ~30 seconds
Fallback
Lyria is experimental. If generation fails with a policy error or returns no music, the script will attempt to retry once with a simpler fallback prompt: "Create a 30-second simple ambient background track. Instrumental only, calm and neutral."
If the fallback attempt also fails, the pipeline proceeds without background music — the audio-mixing step handles this gracefully.
