- MessagesCubit: 1:1 conversation over MessageTransport. Filters the shared inbox to the peer; tags our own sends with our pubkey (NIP-17 wraps don't come back to the sender) so the UI can align bubbles; degrades gracefully offline. - ChatScreen (mockup 10): message bubbles (mine right / peer left) + a composer; opens a session lazily, shows 'set up sharing' when there's no relay. - Entry point: a 'Message' button on each offer card (hidden on your own listings) → /chat/:pubkey. - Routing + i18n en/es/pt. Tests: 5 cubit (send/receive/order/filter/offline) + chat offline + market, green.
