+## Locale (FA / EN)
+
+Dashboards support **Farsi + English** via shared `LocaleProvider` (`@meshkee/dashboard-ui`) and `LanguageSelect` in headers.
+
+| Piece | Where |
+|-------|--------|
+| Locale state | `packages/dashboard-ui` → `LocaleContext` |
+| Default language per business | `settings.branding.defaultLocale`: `'fa' \| 'en'` (default **`fa`**) |
+| Applied on open | Business + customer `TenantBrandingProvider` once from tenant branding |
+| Super-admin edit | Businesses list **Lang** column + edit modal |
+| Business UI copy | `apps/business/src/i18n/messages.ts` + `useT()` |
+| Customer UI copy | `apps/customer/src/i18n/` (parallel pattern) |
+| Document titles | Locale-aware via `routeTitles` + `useDashboardDocumentTitle` |
+| Fonts | `--font-ui: var(--font-en), var(--font-fa)` — see `.cursor/rules/ui-farsi-fonts.mdc` |
+
+RTL: `dir="rtl"` when locale is `fa`.
+
+---
+
+## Business home dashboard
+
+Home is **not** a 1:1 mirror of the sidebar. Tiles are curated (no Settings tile).
+
+| Feature | Detail |
+|---------|--------|
+| Section cards | Count pill + arrow (settings/website have arrow only); hover fills primary |
+| Counts | Existing list `total` with `pageSize=1` — light, not a new stats join |
+| Charts (6/12 each) | Orders (+ add-to-basket) and Customers (+ active logins), last 30 days |
+| Chart API | `GET .../orders/activity?days=30`, `GET .../customers/activity?days=30` |
+| Chart colors | Primary series = theme primary; accent = purple for red theme, cyan for blue themes (`--chart-accent` from `businessPrimaryColors`) |
+| Page aura | Slow-moving radial blobs on `body::before` (tokens + business `index.css`) |
+
+Products overview page uses the same i18n + theme-aware `ProductActivityChart` (added vs updated, 12 months).

 ## Suggested next work
 
 - Point `meshkee.com/invoices/*` at the public invoice viewer (proxy or dedicated host)
 - Business-dashboard invoice templates + issue flow (`owner_scope=business`)
-- Migrate business and super-admin to `@meshkee/dashboard-core` / `@meshkee/dashboard-ui`
+- Migrate business and super-admin fully onto `@meshkee/dashboard-core` / `@meshkee/dashboard-ui` (LocaleProvider already shared)
+- Finish FA/EN coverage on remaining business form pages (many labels still English)
 - Connect product comments to backend
 - Wire order status transitions to store `orderProcessSteps`
 - Enforce `onlineSellEnabled` on public website checkout
