   - Không hardcode chuỗi text trực tiếp vào JSX; luôn sử dụng từ điển ngôn ngữ và hook `useLanguage` / `useTranslation`.
   - Lưu trữ lựa chọn ngôn ngữ và theme trong `localStorage` để ghi nhớ cho các phiên tiếp theo.
 - **Vị trí Controls**: Thanh Navbar/Header luôn phải tích hợp `ThemeToggle` và `LanguageToggle` trực quan, dễ thao tác.

+## 8. Quy Chuẩn Đặt Title & Metadata Cho Từng Trang (Page Titles & SEO) - BẮT BUỘC
+Tất cả các trang khi phát triển mới hoặc bảo trì **BẮT BUỘC PHẢI CÓ TIÊU ĐỀ (PAGE TITLE) VÀ METADATA ĐẦY ĐỦ**:
+- **Title Template cấu hình tại `src/app/layout.tsx`**:
+  ```tsx
+  export const metadata: Metadata = {
+    title: {
+      default: "Bảng Điều Khiển | Data Crawler System",
+      template: "%s | Data Crawler",
+    },
+    description: "Hệ thống quản lý và giám sát tác vụ cào dữ liệu web realtime...",
+  };
+  ```
+- **Quy tắc khi tạo Trang Mới**:
+  - Nếu `page.tsx` là **Client Component** (`"use client"`): Vì Next.js App Router cấm export `metadata` từ Client Component, luôn tạo thêm file `layout.tsx` (Server Component) trong cùng thư mục route để export `metadata` và pass through `children`:
+    ```tsx
+    import type { Metadata } from "next";
+
+    export const metadata: Metadata = {
+      title: "Tên Trang",
+      description: "Mô tả ngắn gọn về chức năng của trang",
+    };
+
+    export default function PageLayout({ children }: { children: React.ReactNode }) {
+      return children;
+    }
+    ```
+  - Nếu `page.tsx` là **Server Component**: Export trực tiếp `export const metadata: Metadata = { title: "Tên Trang", description: "..." }`.
+- **Danh sách Title chuẩn các trang hiện tại**:
+  - `/` (Dashboard / Trang chủ): `Bảng Điều Khiển | Data Crawler System`
+  - `/login`: `Đăng Nhập | Data Crawler`
+  - `/register`: `Đăng Ký Tài Khoản | Data Crawler`
+  - `/forgot-password`: `Quên Mật Khẩu | Data Crawler`
+  - `/reset-password`: `Đặt Lại Mật Khẩu | Data Crawler`
+  - `/verify-email`: `Xác Thực Email | Data Crawler`
+  - `/forbidden`: `Truy Cập Bị Từ Chối (403) | Data Crawler`
