Collaborative Whiteboard
Draw together in real time, browser-to-browser over a WebRTC data channel — no server in
the middle. Connect two devices by copying a one-time code between them; after that, strokes and cursors
travel directly peer-to-peer. You can also just draw here solo.

One of you hosts: create an invite code and send it over (chat, email, anything).
The other joins: paste it, generate a reply code, send that back.
Host pastes the reply → you're drawing together, peer-to-peer.
