+## 8. Quy Chuẩn Giao Diện Dropdown & Đa Ngôn Ngữ (Dropdown & i18n Standards)
+- **Quy chuẩn Custom Dropdown (ThemeToggle Pattern)**:
+  - **TUYỆT ĐỐI KHÔNG** dùng thẻ `<select>` mặc định của trình duyệt cho các bộ chọn tùy chỉnh trong modal/form.
+  - Bắt buộc thiết kế Custom Dropdown theo phong cách của `ThemeToggle`:
+    - **Trigger Button**: Bo góc mềm `rounded-2xl`, viền `border-border/80`, có icon phân loại, tên tùy chọn đang chọn và icon `<ChevronDown />` xoay 180° khi mở (`isDropdownOpen ? "rotate-180" : ""`).
+    - **Menu Popup**: `absolute` có `rounded-2xl border border-emerald-500/20 bg-card/95 p-1.5 shadow-xl shadow-emerald-950/10 backdrop-blur-xl z-50 animate-in fade-in-50 zoom-in-95 duration-150`.
+    - **Option Item**: Thẻ `button` bo góc `rounded-xl px-2.5 py-2 text-xs flex items-center justify-between`. Khi được chọn (`isSelected`), hiển thị nền xanh nhẹ `bg-emerald-500/10 text-emerald-600 dark:text-emerald-400 font-semibold border border-emerald-500/20` kèm icon `<Check />`.
+    - **Xử lý đóng an toàn**: Sử dụng `useEffect` lắng nghe `mousedown` bên ngoài (`contains(target)`) và phím `Escape` để tự động đóng dropdown.
+- **Quy chuẩn Đa Ngôn Ngữ (i18n)**:
+  - **Bản dịch Tiếng Việt thuần túy**: TUYỆT ĐỐI KHÔNG mở ngoặc kèm từ tiếng Anh hay ký hiệu thừa trong nhãn tiếng Việt (ví dụ: cấm `(Target URL)`, `(Depth)`, `(Normal)`, `(JSON)`, `(+)`, `(~)`, `(-)`, `(=)`).
+  - **Đồng bộ hóa 100% Tiếng Anh**: Mọi khóa trong `translations.vi` đều phải có khóa tương ứng trong `translations.en`.
+  - **Định dạng ngày tháng theo Locale**: Hàm `formatDate(date, locale)` bắt buộc phải nhận `locale` từ hook `useLanguage()`, định dạng `en-US` khi Tiếng Anh và `vi-VN` khi Tiếng Việt để tránh dính chữ tiếng Việt (như `thg`) trên giao diện tiếng Anh.
