Wires the 'coming soon' market card to a real discovery screen (mockups 04/05):
- MarketScreen: opens an OfferTransport lazily; local-first, so it degrades to a
human 'set up sharing' prompt when no relay/area is set or the net is down.
- Discovers offers by the saved coarse area, lists them with human reciprocity
labels (gift/swap/for sale), 'near you' (never exact location), price only for
sales. Config sheet to set area + community servers (no bundled public relays).
- Threaded via TaneApp(social, socialSettings) — null keeps the card 'coming
soon' (so Block 1 tests pass unchanged); main wires it live.
- i18n en/es/pt (market.*), reuses share.* for type labels.
3 market widget tests + home tests green; app_seeds analyzes clean.
- Add rtl_smoke_test covering inventory, detail (lot sheet) and settings
under Directionality.rtl, with an Arabic label and vernacular name.
- Ship pt.i18n.json (Portuguese) as proof the locale pipeline scales beyond
es/en; wire its language tile in Settings.
- docs/i18n.md documents the Weblate-ready flow for adding locales.
