…egory format

- Add import-file schemas: metadataSchema, fieldSchema, categorySchema, comapeoCatSchema
- Vendor 5 representative category + 10 field fixtures from comapeo-default-categories v1.1.2
- Add loadDefaultCategoryFixtures() fixture loader
- Export new schemas from barrel index
- 54 tests covering valid/malformed/edge cases for all schemas

…elect unwrap

- Add iconRef to PresetInput interface in useCategories
- Remove unused Card import from CategoryCard
- Fix duplicate useNavigate mock in test
- Add select: (data) => data.data to usePresets for backward compat
- Fix test assertions for unwrapped data shape

… a11y

- useCategorySets: add error state + .catch on toArray() and refresh
- ImportSetDialog: useEffect cleanup for auto-close timer, try/catch on replace
- categories-db: remove dead getCategoriesDb singleton
- CategoriesEditor: add aria-label to search input

- CategoriesEditor: show 'Select a project' message when no project selected (stops eternal skeleton)
- FieldViewer: fix select_one/select_multiple → selectOne/selectMultiple to match Valibot enum

…, iconRef/color, replace flow, useCategorySets

Addresses all 4 MEDIUM findings from claude-qwen test-coverage review:
- CategoryCard: click/keyboard selection + aria-pressed tests (10 tests)
- useCategories: iconRef & color branch coverage (4 tests)
- ImportSetDialog: replace-execution + file-read-failure paths (2 tests)
- useCategorySets: new hook test file (4 tests — empty, populated, error, refresh)

…ML semantics, serverConfig hygiene

- Add missing pt/es translations for new field-type messages; remove stale
  uncategorized/fieldCount/fieldType.unknown keys from pt/es
- Gate resolvedFields on fieldsQuery.isPending to avoid 'Field unavailable'
  flash during initial fields load
- Replace invalid <h3> inside <button> with <span> (valid content model)
- Stop threading full {baseUrl, token} through UI props; CategoryIcon and
  the chain now take serverBaseUrl (string | null) only
- Add tests: unresolved fieldRef → 'Field unavailable' (no raw docId),
  fields-pending hold, empty geometry:[] exclusion

… valid phrasing content

…onse

- ObservationCategoryIcon: add m-auto to the icon <img> and fallback
  letter so the SVG is centered inside its circle. PR #147 switched sizing
  to fixed width/height inside an absolute inset-0 box, which anchored the
  icon to the top-left corner, breaking horizontal/vertical centering.
- fieldSchema: a real archive /field response can omit optional keys such
  as "universal" (and may carry extra keys like "geometry"). The previous
  strict v.object rejected those fields, throwing on parse and making the
  entire fields fetch fail to load. Make "universal" a tolerant
  v.fallback(boolean, false) so a missing key defaults to false while the
  output type stays boolean and downstream consumers are unaffected.

RED to GREEN via tests: field.test.ts (real server-shaped field) and
ObservationCategoryIcon centering test.

Real Mapeo archive server returns `tagKey` (not `key`) and camelCase
field types (`selectOne`/`selectMultiple`). The previous fieldSchema required
`key` + snake_case, so v.parse threw on every /field response in prod,
getFields rejected, useApiFields errored, and CategoriesEditor showed
"Field labels unavailable".

- schemas/field.ts: fieldSchema accepts tagKey and key (both optional),
  accept selectOne/selectMultiple alongside select_one/select_multiple
- fields/normalize.ts: API_TYPE_MAP maps camelCase types; normalizeApiField
  reads tagKey ?? key ?? ''
- remote-archive.ts pullFields: map archive tagKey into Dexie `key` column
  (no migration)
- fixtures: real-archive-response.json (4-field capture incl. 1 deleted);
  presets fieldsFixture key -> tagKey
- tests: field/normalize/useApiFields unit coverage + field-resolution proof
  test (real MSW /field response: labels render, no error banner, deleted
  field excluded)

Reviewed by Opus 5 (Round 2): APPROVED, no pre-merge blockers. Closes #143.

Gap A — Flaky LoginScreen test ("window is not defined" unhandled rejection):
  guard setSubmitState behind a mountedRef so async handleSubmit cannot
  schedule a React update after unmount/teardown.

Gap B — fieldSchema required createdAt/updatedAt; now v.fallback(v.string(),'')
  to match remote-archive.ts pullFields (which already writes ?? '').
  Removes the dead/tolerant mismatch; output type stays string.

Gap C — buildFieldLookup now skips deleted fields by default
  (includeDeleted opt-in); adds regression tests in normalize.test.ts.

Gap D — document that Dexie Field.type is stored un-normalized camelCase.

Verified: tsc --noEmit clean, prettier clean, 57 unit tests pass
(incl. field-resolution proof + new gap tests). screenshots/ left untouched.

1. ObservationCategoryIcon size regression: inline style overrides
   Tailwind classes. Two pre-existing callers (DataScreen h-12 w-12,
   ObservationsMap h-7 w-7) rendered at default 32px. Changed to
   pass explicit size={48} / size={28}. Added regression test.

2. Wire ImportSetDialog into CategoriesEditor toolbar. The dialog
   was fully implemented + tested but unreachable. Added Import
   button, isImportOpen state, i18n key (en/pt/es). Added tests
   for button render + dialog open on click.

Addresses Opus 5 final readiness gate findings (PR #147).

…buttons

- Replace dead hover:bg-primary-dark (undefined CSS var) with hover:bg-primary-hover on all 3 buttons
- Add min-h-[44px] to Import button for mobile touch-target compliance

The import flow writes to IndexedDB but the screen reads from the
server API — the two data sources are disconnected. Commenting out
the UI until the full flow is implemented.

Tracked in #151.

- Comment out Import button + ImportSetDialog render in CategoriesEditorScreen
- Comment out 2 import dialog wiring tests
- Update PR title/description to remove 'import' from scope
