Two gaps kept the wallet QR scanner camera-less outside a desktop browser:
- Companion app: the WebView's default WebChromeClient silently denies
getUserMedia. Both WebViews (main + in-app overlay) now implement
onPermissionRequest — granting video capture only, requesting the
app-level CAMERA permission on first use (manifest already declares it).
- Plain-http origins (mobile web/PWA on a LAN node): browsers hide
navigator.mediaDevices entirely, no permission can bring it back. New
"Take photo of QR" fallback uses <input capture=environment> — the
native camera needs no secure context — and decodes the shot locally
with qr-scanner's scanImage. Live preview still used when available.

New WalletScanModal scans QR codes with the device camera (BarcodeDetector
with jsQR fallback) including animated/multi-frame QRs via qrloop, then
routes what it saw: BOLT11 invoices -> lightning pay (amount locked from
the invoice when present), bitcoin:/BIP21 URIs -> on-chain send, Cashu
tokens -> redeem, Fedimint invites -> join. Entry points: camera button on
the wallet card (far right), and a Scan button centered between the
Close/Send and Close/Receive buttons of both modals.
