// AudioProgress is one persisted resume point for the floating audio
// player — the last-known playback position of a single audio file for a
// user. Key is the track URL with query/hash stripped (the stable file
// identity, owned by the frontend). Position/Duration mirror the
// HTMLAudioElement's currentTime/duration in seconds. UpdatedAt is set by
// the client so multi-device writes resolve newest-wins on upsert.
