libp2p WebRTC QR

Connect two browsers directly by exchanging signed WebRTC offer and answer QR codes.

1. Start browser peer

Peer ID: not started

2. Exchange QR payloads

Browser A: create an offer. Browser B: scan A's offer and show the generated answer. Browser A: scan B's answer. Do not process a browser's own QR code.

QR payload or copy/paste fallback

For reliable scanning, turn up the other screen's brightness, keep the QR code flat, and let it fill about half of the camera view.
