+# App i18n
+
+Client-side UI string localization for the product client (`toju-app`), using the same `@ngx-translate/core` stack as the marketing website.
+
+## Responsibilities
+
+- Bundle locale JSON under `toju-app/public/i18n/`.
+- Bootstrap translations at app startup via `AppI18nService` (root `App` constructor).
+- Expose `APP_TRANSLATE_IMPORTS` for standalone components that use the `translate` pipe in templates.
+- Resolve the active locale through `resolveAppLocale()` in `app-i18n.rules.ts`.
+
+## Boundaries
+
+- **In scope:** user-visible UI copy in the Angular product client.
+- **Out of scope:** server error messages, plugin-authored strings, Electron IPC payloads, and marketing-site copy (`website/public/i18n/`).
+
+## Key files
+
+| Path | Role |
+|------|------|
+| `toju-app/public/i18n/en.json` | English translation catalog (only locale shipped today). |
+| `toju-app/src/app/core/i18n/app-i18n.rules.ts` | Supported locales and locale resolution. |
+| `toju-app/src/app/core/i18n/app-i18n.service.ts` | Loads bundled JSON into `TranslateService`. |
+| `toju-app/src/app/core/i18n/app-translate.imports.ts` | `TranslateModule` import bundle for standalone components. |
+| `toju-app/src/app/app.config.ts` | `provideTranslateService()` registration. |
+
+## Usage
+
+**Templates** — import `APP_TRANSLATE_IMPORTS` in the standalone component and use the pipe:
+
+```html
+{{ 'common.brand' | translate }}
+```
+
+**TypeScript** — inject `AppI18nService` (or `TranslateService`) and call `instant()`:
+
+```ts
+this.appI18n.instant('common.brand');
+```
+
+## Catalog workflow
+
+User-visible strings live in fragment files under `toju-app/public/i18n/catalog/*.json`, merged into `toju-app/public/i18n/en.json` by:
+
+```bash
+npm run i18n:sync
+```
+
+The sync script also extracts `theme.registry.*` labels/descriptions from `theme-registry.logic.ts` and `permissions.*` from `access-control.constants.ts` so those large registries stay DRY. Extracted prefixes use dotted paths and are merged as nested JSON (e.g. `theme.registry.appShell.label`, not a flat `"theme.registry"` root key).
+
+## Adding a locale later
+
+1. Add `toju-app/public/i18n/catalog/*.json` fragments for the new locale (or mirror `en.json` structure).
+2. Register the locale in `SUPPORTED_APP_LOCALES`.
+3. Import and `setTranslation()` in `AppI18nService`.
+4. Wire user preference (e.g. general settings) to `AppI18nService.initialize(preferredLocale)`.
+
+## Tests
+
+- `toju-app/src/app/core/i18n/app-i18n.rules.spec.ts`
+- `toju-app/src/app/core/i18n/app-i18n.service.spec.ts`
+- `toju-app/src/app/core/i18n/app-i18n.testing.ts` — `provideAppI18nForTests()` / `initializeAppI18nForTests()` for Vitest injectors

 - Context menus and modal dialogs auto-render as bottom sheets on mobile. `ContextMenuComponent` and `ConfirmDialogComponent` (in `src/app/shared/components/`) inject `ViewportService` and switch their templates between the desktop popover/centered modal and `BottomSheetComponent` (`src/app/shared/components/bottom-sheet/`) on phone-sized viewports. New menus/dialogs should reuse these components rather than rolling their own `fixed inset-0` overlay. For one-off bespoke surfaces, render `<app-bottom-sheet>` directly when `isMobile()`.
 - Tap targets on interactive controls should be at least 44px on mobile. Use `min-h-11` (or explicit `h-11 w-11`) for icon buttons that are tap-only on mobile; desktop sizes can remain smaller via `md:` overrides.

+- User-visible UI strings use `@ngx-translate/core` (same stack as `website/`). Edit fragment catalogs in `public/i18n/catalog/*.json`, then run `npm run i18n:sync` from the repo root to regenerate `public/i18n/en.json`. Only `en` ships today.
+- Bootstrap and locale rules: `src/app/core/i18n/`. Import `APP_TRANSLATE_IMPORTS` in standalone components that use the `translate` pipe; use `AppI18nService.instant()` in TypeScript.
+- Vitest harnesses: `provideAppI18nForTests()` from `src/app/core/i18n/app-i18n.testing.ts`.
