+    helpers** (`skateTime`, `distanceReadout`, `maneuverDescriptor` →
+    `MODE_LABEL_KEYS`/`MANEUVER_LABEL_KEYS` static maps, `routeCache.formatAge`).
+  - `sasquatchUi.*` — `SasquatchGuide`, `SasquatchProDialog`, `SasquatchActionCard`,
+    `SasquatchAiStatusCard`, plus `sasquatchPro.ts` `PRO_TIERS.labelKey/badgeKey`
+    and `useSasquatchActions.summarizeDraft(d, t)`. **LLM system prompts and chat
+    bodies stay English** (the model is language-directed separately).
+  - `collectionUi.*` / `bootUi.*` — `AddToCollectionDialog` placeholders,
+    `SplashScreen` status lines.
+  - `labelsUi.*` (221 keys) — the **shared data-module labels**: spot categories/
+    features/types, access, shelter, event types, gear categories/conditions,
+    price/listings, tours, crews, member-visibility, tag categories, spot status.
+    `src/lib/labelKeys.ts` holds the shared `*_KEYS` value→key maps (single

+    **`src/lib/dateFnsI18n.ts`** re-exports `date-fns` with
+    `formatDistanceToNow`/`…Strict`/`formatDistance`/`format` defaulting to the
+    active locale, plus `dateLocaleCode()` for native `toLocale{Date,Time}String`.
+    `LanguageProvider` calls `setDateLocale(language)` **during render** so the
+    first paint is in-language. **Import from `@/lib/dateFnsI18n`, not
+    `date-fns`.** Number `.toLocaleString()` calls are deliberately left on the
+    runtime default.
+- **Still to translate (batch 4):** the **Lab `*_LABELS`/`*_DESCRIPTIONS` maps**
+  in `src/lib/types.ts` (coach/filmer/editor/photo/builder/artist/graffiti/tattoo/
+  trainer/musician/judge/organizer/barber — ~35 maps), `TOUR_SKILL_LEVELS`, the
+  Sasquatch **static FAQ / local-result chat bodies** and `usePurchasePro` receipt
+  prose, and remaining **feed-supplied vs app-word** distinctions. `TagCategory`
+  names/descriptions have keys but no component renders them. Grep a module
+  before assuming it is translated.
 - ⚠️ A batch-2 agent dropped the `socialUi.` namespace prefix in ~36 files — the
   `check:i18n` guard caught all 738 usages. **Always run `node scripts/check-i18n.mjs`
   (it's in `npm test`) after wiring a file.**
