"""The audio-rendering task against a real database.

From RENDERING, the task synthesises and merges the approved transcript, stores
the bytes, and marks the podcast READY with the storage location recorded. The
DB, service, renderer orchestration, and storage wrapper run for real; the true
externals are faked — the TTS provider, the FFmpeg merge, and the object store.
