- Use BarcodeDetector API (Chrome/Edge/Android) as primary QR scanner; it uses
native OS-level decoding which is far more reliable than jsQR for Prismatic's
QR codes. Falls back to jsQR (attemptBoth) on Safari/Firefox.
- Keep MediaStream alive between modal opens so the browser does not re-prompt
for camera permission on each scan within the same page session. Stream is
released after 2 min of idle (IDLE_RELEASE_MS) or on page unload.
- stopCamera() split into stopQrLoop() (cancel rAF only) and releaseCamera()
(stop tracks + null srcObject); modal hide now calls stopQrLoop, not releaseCamera.
