Server instructions

Lacuna generates AI music. Call `generate_music` to submit a task — it returns immediately with a `pending` task id, because rendering takes roughly 30–120 seconds. Poll `get_generation` with that id until status becomes `ready` (audio URLs are attached) or `failed`. Do not busy-loop: wait ~10 seconds between polls. Each task spends credits from the authenticated account, so confirm with the user before generating repeatedly.
