Ready. Start explicitly to begin.
Start requests camera permission without microphone access. Stop releases it. Camera preference changes require another explicit Start.
What this test can show
Camera access is requested only on Start, on HTTPS or localhost, with browser permission. Audio is never requested. The preview is live and local: no recording, snapshot storage, remote links or upload. Facing direction and dimensions are preferences, not guarantees. Reported frame rate is a delivered track setting, not a measured dropped-frame analysis. Stop, hidden tab, switching or exit releases every camera track.
