Export
- Both stores already held the audio (server /audio-backups/:id/audio and
the local IndexedDB record) but nothing exposed it, so a recording could
not be taken out of the app. Each backup row now has a download, naming
the file by its timestamp and using the extension actually recorded
(webm, or m4a on iOS). A local record is only handed over to the account
that owns it.
Robustness
- MediaRecorder had no onerror and nothing watched the audio track, so a
recorder that failed, or a microphone claimed by another app, unplugged,
or revoked, left the tab saying "recording" while capturing nothing.
Both are now reported once, with the chunks captured so far kept, so
stopping still returns the audio up to the failure.
Deliberately not added: a wake lock. Stopping when the screen sleeps or the
session ends is the intended behaviour — recording is meant to be
deliberate, and nothing is left behind.
