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.
