Reported: while the model downloads, the phone screen locks, the browser discards
the backgrounded tab, and on return the recording is gone (a general mobile SPA
state-loss pattern).
- useWakeLock: hold a screen Wake Lock during transcription/download so the phone
doesn't auto-lock (re-acquired on返回 to foreground). Prevents the discard.
- recording-store (IndexedDB): persist the last recording and restore it on load,
so even if the tab IS discarded, the recording comes back ('Restored your last
recording.'). Blobs can't live in localStorage, hence IndexedDB.
