What this teaches: every message is sealed to Dana's key before it leaves your device — the network routes envelopes, it can't read them. Payments ride the same envelope plus a receipt anchor. This demo uses base64 to show the shape only — real Qalchat envelopes are X25519 key-agreement + XSalsa20-Poly1305 authenticated encryption.
