🛰️ WebRTC, no server two browsers, talking directly
A chat where the messages travel browser-to-browser — encrypted,
peer-to-peer, no server relaying anything. The only "infrastructure" is you, copy-pasting two
blobs of text between the peers (which in real life travels over any channel: a signaling server,
a QR code, an email, a carrier pigeon).
Peer A: Create offer, copy the blob to Peer B's "paste offer" box → Accept.
Peer B: copy the answer blob back to Peer A's box → Finish. Linked. Chat.
