- Remove RGB brightness: firmware 2.1.2 stores the value but the LEDs
never change, so the control did nothing. PROTOCOL.md notes why.
- Lock the device per transaction (flock) so the CLI and the web
service can't interleave and steal each other's replies.
- Detect a mic that is plugged in but no longer answering and tell the
user to replug it (a USB reset is not enough; settings survive).
Seen when hardware buttons are held while settings are being written.
- Web page keeps the last known value when a poll comes back partial,
instead of drawing unanswered settings as off.
- New screenshot.
