Notes
Use HTTPS for camera & WebRTC
Connection is peer-to-peer using WebRTC data channels and a public STUN server. We do zero
signaling on a backend. You link devices by copy/paste or QR.
No persistence: nothing is stored; if you reload this page, selections and received blobs are gone.
On restrictive networks (corporate/guest Wi-Fi), P2P can be blocked by NAT/firewall rules.
Folder upload depends on your browser (Chrome/Edge supported; others may vary).
Debug / Self-tests
These tests verify encoding/decoding, CRC32, and ZIP building. They run entirely in your browser.
