[ptt-audio] recorder.stop() threw

Error message

[ptt-audio] recorder.stop() threw

What it means

Recoverable guard in finalizePttAudio(): calling .stop() on a MediaRecorder whose state changed between the check and the call (or that the browser invalidated) throws synchronously. The catch warns and the flow continues waiting for the already-registered 'stop' event promise, so finalization still settles — the message records a hiccup, not a lost recording.
