9// No server of our own. Relay: ntfy.sh (free, no sign-up). Each person's inbox is a topic derived from their public key.
10// ID = X25519 public key. Every message is sealed to its recipient with nacl.box: only the recipient can open it,
11// and the sender is authenticated. A group message is sealed and sent to each member on its own.
12// Friends run an ML-KEM-768 handshake; after it, the message key comes from both the X25519 and the ML-KEM
13// secrets (hybrid, quantum-resistant).
14// Nicknames stay on this machine and are never sent.
15// Messages never reach Claude on their own: the user presses "↗" in the pane.
