Adds Asturianu, translated in full (345 strings), plus the wiring to
make a minority language work end to end — the OS language picker is an
unreliable way to reach it, so the in-app choice must be explicit and
remembered.
- Model Asturian as the real `ast` locale (honest, international-by-design),
not a fake `es-AST` region — slang rejects a 3-letter region anyway.
- Flutter ships no Material/Cupertino/intl localizations for `ast`, so map
the framework chrome to Spanish (`materialLocaleFor`); the app's own text
stays Asturian via slang. Fixes an "Invalid locale ast" crash when the
auto-backup date was formatted with intl.
- Persist the picked language in the keystore (LocaleStore) and restore it
at startup so it survives restarts and wins over the device locale.
- Settings: add the Asturianu tile; compare the full AppLocale so `es` and
`ast` aren't both marked selected.
Tests: LocaleStore round-trip, locale switch + Spanish-chrome fallback,
and a regression for the intl date crash under Asturian.
- 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.
Interchange export/import for Phase 1 (data-model §7):
- JSON: canonical, versioned envelope (formatVersion 1) with all sync
metadata verbatim, photos embedded as base64, tombstones excluded.
Species are re-resolved on import by scientific name (catalog ids are
per-install). Reader tolerates unknown fields/enum values (§5.2) and
rejects newer format versions with a clear error.
- CSV: export-only spreadsheet flatten, one row per lot, RFC 4180
escaping, never any photo bytes.
- Import merges by UUIDv7 id in one transaction: insert-if-unknown
preserving original stamps, last-writer-wins by packed HLC for known
mutable rows, append-only movements; afterwards the local clock
receiveEvent()s the newest imported stamp so it never runs behind.
- Settings gains a Backup section (export CSV/JSON, import JSON with
confirmation); file dialogs behind a FileService interface backed by
file_picker (MIT).
- Tests: codec round-trip and tolerance, reconciler LWW, repository
export→import round-trip (fresh DB, idempotent re-import, newer-local
wins, clock monotonicity, species re-resolution), backup widget flows.
Apply a Material 3 seed-green palette and rounded components across the
home, inventory, quick-add, quantity picker and variety-detail screens.
The full-screen photo viewer can now set any photo as the cover (via
attachment sort order) and delete after confirmation. Lot forms and
packaging surface as choice chips.
Extract About out of Settings into its own screen (app version via
package_info_plus, website link). Add es/en strings for the new lot
types, presentation, home tagline and About. Update Seedees v2 mockups.
- Bundle the real sprout logo (docs/logo.png → assets/logo.png) and show it on
the home menu instead of a Material icon.
- Settings screen: switch language (Español / English / system) via slang, plus
an About tile (logo, app name, one-line description). Drawer "Settings" is now
active and routes to /settings.
Tests: drawer Settings opens the screen and shows the language options. 54 green.
