A new key means your future strokes have a new owner. Strokes already on the canvas stay under the old key.

Sign locally. Each stroke becomes a canonical JSON event, hashed with SHA-256 and signed with your Ed25519 key.

Relay, don't interpret. Rabta verifies the signature, stores opaque data in SQLite and expires it automatically.

Sync it. Every visitor polls for new strokes and catches up automatically after a reconnect.
