Feedback: the blank 'web address' field was unusable — nobody knows what to put,
so the market never worked at first launch.
- SocialSettings ships default public relays (nos.lol, relay.damus.io), applied
automatically for new users so the market works day one. An explicitly empty
choice still turns the network off (privacy). Exposure is minimal: offers are
opt-in and carry only a coarse geohash.
- Sharing setup now shows the servers as a short PICK-LIST (checkboxes, pre-
selected) instead of a blank field; a community's own server goes under a small
'add another' escape hatch. Intro reworded — no need to know a community.
- Tests updated (defaults) and pinned offline (setRelayUrls([])) so widget tests
don't hit the network. 22 green, analyzer clean.
- 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.
