vjrj f17ae7751c perf(market): paginate Nostr offer discovery, infinite scroll, memory cap 
Bound market memory and let large areas page instead of loading everything:
- DiscoveryQuery gains an until cursor; OfferTransport gains discoverPage()
  (one-shot, EOSE-bounded, newest-first) alongside the existing live discover()
  stream, which now accepts since so it only carries NEW offers going forward.
- NostrOfferTransport.discoverPage sorts by created_at desc and derives the
  next cursor from the oldest event seen (not the oldest type-matched one, so
  filtering never skips a page).
- OffersCubit: discover() fetches the first page + opens a since=now live sub;
  loadNextPage() pages further back; the in-memory list is capped at 400
  offers (each can carry a ~40KB inline photo thumbnail, so unbounded growth in
  a busy area was a real OOM risk).
- market_screen: infinite scroll via a scroll-position trigger + footer
  spinner, instead of a single unbounded ListView.
- Added discoverPage unit tests (commons_core) and cubit pagination tests
  (first page/cursor, accumulation, cap, cross-page dedup).

Localized app screenshots

Golden-based harness that renders key screens as PNGs in several languages, for the landing site (tane.comunes.org) and the app-store listings. No emulator — it runs under flutter test, so it's deterministic and CI-friendly.

Regenerate

cd apps/app_seeds
flutter test --update-goldens --run-skipped --tags screenshots test/screenshots/screenshots_test.dart
tool/collect_screenshots.sh   # copy PNGs into site/ and fastlane/

Drop --update-goldens to verify the committed PNGs still match. The screenshots tag is skipped by default (dart_test.yaml) — so it never runs in the normal suite or CI's flutter test --coverage, where golden pixel differences across OS/font versions would cause false failures. --run-skipped opts it back in.

What it produces

goldens/<locale>/<screen>.png for en, es, fr, de, pt, ja, screens home · inventory · market · calendar · detail, plus goldens/rtl/inventory.png. The market is rendered populated via a seeded OffersCubit with a no-op transport (no network); home/calendar/detail/inventory render from the repository alone.

  • Fonts: real glyphs come from loadScreenshotFonts() — every family in FontManifest.json (MaterialIcons + bundled Noto/seedks) plus the bundled DejaVu Sans as the Latin text face. No Roboto needed.
  • rtl/ is a layout demo, not a locale: English strings forced right-to-left to prove the design is RTL-safe. The app ships no Arabic translation yet, so there is deliberately no ar/ with Arabic copy.
  • Partial locales (e.g. ja) fall back to English for untranslated strings — that's the app's real runtime behavior, shown honestly.
  • These are raw device-canvas frames (no marketing captions or device bezels). Add those downstream only if a store rejects plain screenshots.

Adding a screen or locale

Edit screenshotLocales / the screens map in screenshots_test.dart. Screens must render from the repository + cubits alone (no live Nostr/network stack), so inventory/detail/calendar are the safe, self-contained set.
