Cross-device sync
If you set an APP_PASSCODE on your Cloudflare deployment, enter it here to enable
syncing. With no passcode set, sync is open (single-user) once D1 is wired.
Backup
Export a JSON snapshot of all your progress, or restore from one. Useful before clearing browser data or moving devices.
Reset
Clear every checkbox and quiz result on this device. This can't be undone (export first if unsure).
