Audio-only playback (AudioOnlySampleApp)

Plays audio-only assets with a media-style background playback notification, so audio and its transport controls keep working when the app is in the background. Layers on:

• a scrollable track list backed by a Brightcove playlist
• shuffle and repeat controls

Key files

File	Responsibility
MainActivity.kt	Loads the playlist via Catalog, wires the shuffle and repeat controls, attaches the background playback notification, and renders the track list.

See the Playback README for shared setup and requirements.
