 ## Current State
 
 - The app uses `useLanguage().t("...")` with dictionaries in `packages/app/src/i18n/en.ts` and `packages/app/src/i18n/zh.ts`.
-- Recent progress (already translated): `packages/app/src/pages/home.tsx`, `packages/app/src/pages/layout.tsx`, `packages/app/src/pages/session.tsx`, `packages/app/src/components/prompt-input.tsx`, `packages/app/src/components/dialog-connect-provider.tsx` (plus new keys added in both dictionaries).
-- Dictionary parity check: `en.ts` and `zh.ts` currently contain the same key set (314 keys each; no missing or extra keys).

-**Recommendation:**
-- Translate all framing/UI labels and action buttons.
-- Decide whether to translate highly technical diagnostics. A good compromise is:
-  - Translate the labels ("Caused by", "Unknown error", "Status")
-  - Keep raw messages from servers/providers as-is
+- Localized page UI copy via `error.page.*` keys (title, description, buttons, report text, version label).
+- Localized error chain framing and common init error templates via `error.chain.*` keys.
+- Kept raw server/provider error messages as-is when provided (only localizing labels and structure).
