+# 代码编写规范
+
+本文档定义了 Testing Tools 浏览器扩展项目的编码规范和最佳实践。所有代码贡献者应遵循这些规范以保持代码库的一致性和可维护性。
+
+## 1. TypeScript 规范
+
+### 1.1 类型定义：`interface` vs `type`
+
+- **`interface`**：用于组件 Props、对象结构、Context 类型等可扩展结构
+- **`type`**：用于联合类型、工具类型、不可扩展的类型别名
+
+```typescript
+// ✅ interface — 组件 Props / 对象结构
+export interface GlobalSnackbarProps {
+  message: string;
+  open: boolean;
+  onClose: () => void;
+  severity?: SnackbarSeverity;
+}
+
+// ✅ interface — 继承 HTML 属性
+interface LiveClockProps extends React.HTMLAttributes<HTMLDivElement> {
+  unit: UnitType;
+  onUseNow: (val: number) => void;
+}
+
+// ✅ type — 联合类型
+export type ThemeMode = 'light' | 'dark' | 'system';
+export type PageType = 'dashboard' | 'timestamp' | 'storageCleaner' | ...;
+
+// ✅ type — 工具类型
+export type ResolvedThemeMode = 'light' | 'dark';
+```
+
+### 1.2 泛型使用
+
+广泛使用泛型约束，结合 `extends` 进行类型守卫：
+
+```typescript
+// ✅ 泛型 + extends 约束
+export interface SwitchOption<T extends string | number = string> {
+  value: T;
+  label: React.ReactNode;
+}
+
+// ✅ 泛型 + StorageSchema 键约束
+async get<K extends keyof StorageSchema>(
+  key: K,
+  defaultValue?: StorageSchema[K],
+): Promise<StorageSchema[K] | undefined> { ... }
+
+// ✅ 泛型 Hook
+export const useStorageState = <K extends keyof StorageSchema>(
+  key: K,
+  defaultValue: StorageSchema[K],
+  validator?: (val: unknown) => val is StorageSchema[K],
+) => { ... }
+```
+
+### 1.3 类型守卫
+
+优先使用类型守卫函数（`val is Type` 谓词），避免 `as` 强转：
+
+```typescript
+// ✅ 类型守卫谓词函数
+const isValidMode = (v: unknown): v is ThemeMode => VALID_MODES.includes(v as ThemeMode);
+
+const isValidPage = (page: unknown): page is PageType => {
+  return typeof page === 'string' && (getAllFeatureKeys() as string[]).includes(page);
+};
+
+// ✅ 安全的 as 断言，仅在类型守卫验证后使用
+export function isSupportedImageType(mimeType: string): boolean {
+  return (SUPPORTED_IMAGE_TYPES as readonly string[]).includes(mimeType);
+}
+```
+
+### 1.4 导出模式
+
+| 场景        | 导出方式                                         | 示例                              |
+| ----------- | ------------------------------------------------ | --------------------------------- |
+| 页面组件    | `export default function ComponentName()`        | `pages/Timestamp/index.tsx`       |
+| 业务组件    | `const X = React.memo(...)` + `export default X` | `LiveClock.tsx`, `ResultView.tsx` |
+| UI 原子组件 | `React.forwardRef(...)` + `export { X }`         | `components/ui/button.tsx`        |
+| 工具函数    | `export function xxx()`                          | `utils/clipboard.ts`              |
+| 自定义 Hook | `export function useXxx()`                       | `utils/useStorageState.ts`        |
+| 类型/接口   | `export interface` / `export type`               | `types/storage.d.ts`              |
+
+```typescript
+// ✅ 页面组件 — default export
+export default function Index() { ... }
+
+// ✅ 需要 memo 的组件 — 箭头函数 + React.memo + displayName
+const LiveClock = React.memo(({ ... }: LiveClockProps) => { ... });
+LiveClock.displayName = 'LiveClock';
+export default LiveClock;
+
+// ✅ UI 组件 — forwardRef + 命名导出
+const Button = React.forwardRef<HTMLButtonElement, ButtonProps>(...);
+Button.displayName = 'Button';
+export { Button, buttonVariants };
+```
+
+---
+
+## 2. React 组件规范
+
+### 2.1 组件定义方式
+
+- **标准组件**：使用 `function` 声明
+- **需要 memo 的组件**：使用箭头函数 + `React.memo`
+- **需要 ref 的组件**：使用 `React.forwardRef`
+- **错误边界**：使用 Class 组件（React 要求）
+
+```typescript
+// ✅ 标准页面组件
+export default function Index() { ... }
+
+// ✅ 需要 memo 的组件
+const LiveClock = React.memo(({ unit, onUseNow, className, ...props }: LiveClockProps) => {
+  ...
+});
+LiveClock.displayName = 'LiveClock';
+export default LiveClock;
+
+// ✅ 需要 ref 的组件
+const TextInputArea = forwardRef<HTMLTextAreaElement, TextInputAreaProps>((props, ref) => {
+  ...
+});
+TextInputArea.displayName = 'TextInputArea';
+export default TextInputArea;
+
+// ✅ Class 组件（仅用于 ErrorBoundary）
+export class ErrorBoundary extends Component<Props, State> { ... }
+```
+
+### 2.2 Props 模式
+
+- 使用 `interface` 定义 Props
+- 继承 `React.HTMLAttributes` 以支持原生属性透传
+- 使用 `Omit` 排除冲突属性
+- 解构 `className` 和 `...rest props`
+
+```typescript
+// ✅ 继承 HTML 属性 + className 透传
+interface ResultViewProps extends React.HTMLAttributes<HTMLDivElement> {
+  result: string;
+  mode: 'ts2dt' | 'dt2ts';
+  unit: UnitType;
+  zone: string;
+  showEmptyPlaceholder?: boolean;
+}
+
+// 使用时解构 className 和 rest props
+const ResultView = React.memo(({
+  result, mode, unit, zone,
+  showEmptyPlaceholder = false,
+  className, ...props
+}: ResultViewProps) => {
+  return <div className={cn('flex flex-col w-full', className)} {...props}>...</div>;
+});
+
+// ✅ Omit 排除冲突属性
+export interface TextInputAreaProps extends Omit<
+  React.TextareaHTMLAttributes<HTMLTextAreaElement>, 'onChange'
+> { ... }
+```
+
+### 2.3 状态管理
+
+- **本地状态**：`useState` + 惰性初始化
+- **衍生状态**：`useMemo` 响应式计算管线
+- **持久化状态**：Chrome Storage + `localStorage` 快照
+- **全局状态**：React Context
+
+```typescript
+// ✅ useState + 惰性初始化
+const [input, setInput] = useState(() => String(Date.now()));
+
+// ✅ useMemo 响应式计算管线（零延迟，无需手动 convert 按钮）
+const conversionPipeline = useMemo(() => {
+  const rawInput = input.trim();
+  if (!rawInput) return { result: '', error: '' };
+  // ... 自动计算结果
+}, [input, mode, unit, zone, t]);
+
+// ✅ Chrome Storage 持久化状态
+export const useStorageState = <K extends keyof StorageSchema>(
+  key: K, defaultValue: StorageSchema[K], validator?: ...
+) => { ... }
+```
+
+### 2.4 副作用模式
+
+- **取消标志**：防止异步竞态
+- **ref 回调指针**：保持回调最新避免依赖膨胀
+- **事件监听 cleanup**：始终在 cleanup 中移除监听器
+- **定时器 cleanup**：始终在 cleanup 中清除定时器
+
+```typescript
+// ✅ 取消标志模式 — 防止异步竞态
+useEffect(() => {
+  let cancelled = false;
+  storageUtil.get(THEME_MODE_KEY, 'system').then((saved) => {
+    if (cancelled) return;
+    if (isValidMode(saved)) { ... }
+  });
+  return () => { cancelled = true; };
+}, [updateResolved]);
+
+// ✅ ref 回调指针 — 保持回调最新避免依赖膨胀
+const onUseNowRef = useRef(onUseNow);
+useEffect(() => { onUseNowRef.current = onUseNow; }, [onUseNow]);
+
+// ✅ setInterval + cleanup
+useEffect(() => {
+  const tickId = setInterval(tick, 200);
+  return () => clearInterval(tickId);
+}, [unit]);
+
+// ✅ 事件监听 cleanup
+useEffect(() => {
+  const handleClickOutside = (event: MouseEvent) => { ... };
+  document.addEventListener('mousedown', handleClickOutside);
+  return () => document.removeEventListener('mousedown', handleClickOutside);
+}, []);
+```
+
+### 2.5 `memo` / `useCallback` / `useMemo` 使用
+
+| 场景                               | 使用方式      |
+| ---------------------------------- | ------------- |
+| 高频渲染组件（列表子项、实时时钟） | `React.memo`  |
+| 事件处理函数、回调引用             | `useCallback` |
+| 响应式计算管线、衍生数据           | `useMemo`     |
+| 避免重复创建对象/集合              | `useMemo`     |
+
+```typescript
+// ✅ React.memo — 高频更新组件
+const LiveClock = React.memo(({ ... }) => { ... });
+const ResultView = React.memo(({ ... }) => { ... });
+
+// ✅ useCallback — 事件处理
+const handleUseNow = useCallback((now: number) => {
+  if (mode === 'ts2dt') {
+    setInput(String(unit === 'ms' ? now : Math.floor(now / 1000)));
+  } else {
+    setInput(dayjs(now).tz(zone).format(DATE_FORMAT));
+  }
+}, [mode, unit, zone]);
+
+// ✅ useMemo — 避免重复创建集合
+const visibleSet = useMemo(() => new Set<string>(visiblePages), [visiblePages]);
+```
+
+---
+
+## 3. 导入规范
+
+### 3.1 导入顺序
+
+按来源分组，顺序如下：
+
+1. React 核心
+2. 第三方库（图标、UI 库等）
+3. 业务 Provider / Context
+4. 配置 / 存储
+5. i18n
+6. 本地页面组件
+7. UI 组件
+8. 工具函数 / Hook
+9. 类型
+10. 常量
+
+```typescript
+// 1. React 核心
+import React, { useEffect, useMemo, useRef, useState } from 'react';
+// 2. 第三方库
+import { ArrowLeft, ExternalLink, Globe } from 'lucide-react';
+import { toast } from 'sonner';
+// 3. 业务 Provider
+import { useRouter } from '@/providers/RouterProvider';
+import { useThemeMode } from '@/providers/ThemeModeProvider';
+// 4. 配置 / 存储
+import { FeatureConfig, FEATURES } from '@/config/features';
+import { storageUtil } from '@/utils/chromeStorage';
+// 5. i18n
+import { useTranslation } from 'react-i18next';
+import { normalizeLanguage, SUPPORTED_LANGUAGES } from '@/i18n';
+// 6. 本地组件
+import TextMode from './TextMode';
+import { ZONES } from './constants';
+// 7. UI 组件
+import SwitchButtonGroup from '@/components/SwitchButtonGroup';
+import { Button } from '@/components/ui/button';
+// 8. 工具函数 / Hook
+import { cn } from '@/lib/utils';
+import { useLazyTranslation } from '@/utils/useLazyTranslation';
+// 9. 类型
+import type { PageType, StorageSchema } from '@/types/storage';
+```
+
+### 3.2 路径别名
+
+- `@/` 映射到项目根目录
+- **跨目录导入**：使用 `@/` 绝对别名
+- **同目录导入**：使用相对路径 `./`
+
+```typescript
+// ✅ 绝对别名导入 — 跨目录
+import { cn } from '@/lib/utils';
+import { storageUtil } from '@/utils/chromeStorage';
+import type { StorageSchema } from '@/types/storage';
+import { Button } from '@/components/ui/button';
+
+// ✅ 相对导入 — 仅限同目录
+import TextMode from './TextMode';
+import { ZONES } from './constants';
+import { useTimestampConverter } from './useTimestampConverter';
+```
+
+---
+
+## 4. 样式规范
+
+### 4.1 `cn()` 工具函数
+
+统一使用 `cn()` 合并 Tailwind 类名（来自 `clsx` + `tailwind-merge`），导入自 `@/lib/utils`：
+
+```typescript
+import { cn } from '@/lib/utils';
+
+// ✅ 条件类名 + 合并外部 className
+<div className={cn(
+  'flex items-center gap-3 px-3 h-10 rounded-lg border border-border/80 bg-secondary/50',
+  className,   // 外部传入的覆盖
+)} {...props}>
+
+// ✅ 错误状态变体
+<Input className={cn(
+  'font-mono font-semibold h-10 shadow-sm placeholder:text-muted-foreground/60',
+  error && 'border-destructive focus-visible:ring-destructive',
+)} />
+
+// ✅ 选中/未选中状态
+className={cn(
+  'flex-1 inline-flex items-center justify-center font-medium whitespace-nowrap transition-all',
+  sizeClasses[size],
+  isSelected
+    ? 'bg-background text-foreground shadow-sm font-semibold'
+    : 'hover:bg-background/50 hover:text-foreground/80',
+  buttonClassName,
+)}
+```
+
+### 4.2 主题 / 暗色模式
+
+使用 shadcn/ui 的 CSS 变量语义化类名，**禁止硬编码颜色值**：
+
+```typescript
+// ✅ 语义化颜色 token — 亮/暗模式自适应
+<div className="min-h-screen bg-background text-foreground antialiased selection:bg-primary/20">
+<div className="p-5 rounded-xl border border-border bg-card text-card-foreground shadow-sm">
+
+// ✅ 暗色模式特殊处理
+'fixed ... bg-white dark:bg-gray-900 p-6 ...'
+
+// ✅ 需要固定颜色的特殊场景（如二维码白色背景保护）
+<div className="p-3 bg-white rounded-lg shadow-sm border border-border/40">
+```
+
+**常用语义化 token：**
+
+| 用途 | 类名                                                               |
+| ---- | ------------------------------------------------------------------ |
+| 背景 | `bg-background`, `bg-card`, `bg-muted`, `bg-secondary`             |
+| 文字 | `text-foreground`, `text-card-foreground`, `text-muted-foreground` |
+| 边框 | `border-border`, `border-border/80`                                |
+| 主色 | `text-primary`, `bg-primary`, `border-primary`                     |
+| 危险 | `text-destructive`, `bg-destructive`, `border-destructive`         |
+
+### 4.3 响应式设计
+
+移动优先，使用 `sm:` / `md:` / `lg:` 断点：
+
+```typescript
+// ✅ Grid 自适应布局
+<div className="grid grid-cols-1 md:grid-cols-2 gap-4 items-stretch">
+
+// ✅ Dashboard 自动填充网格
+<div className="grid grid-cols-1 sm:grid-cols-[repeat(auto-fill,minmax(290px,1fr))] auto-rows-auto gap-3.5 p-3.5 w-full h-auto">
+
+// ✅ 弹性方向切换
+<div className="flex flex-col sm:flex-row items-stretch gap-3 w-full">
+
+// ✅ 内边距响应式
+<div className="p-4 sm:p-6 space-y-4">
+```
+
+---
+
+## 5. 错误处理
+
+### 5.1 工具函数：结果对象模式
+
+工具函数**不抛异常**，返回包含 `hasError` 和 `error` 字段的结果对象：
+
+```typescript
+// ✅ 结果对象模式
+export function markdownToHtml(markdown: string): MarkdownToHtmlResult {
+  try {
+    ...
+    return { html, originalLength, htmlLength, hasError: false };
+  } catch (error) {
+    return {
+      html: '', ...
+      hasError: true,
+      error: error instanceof Error ? error.message : 'Markdown 解析失败',
+    };
+  }
+}
+```
+
+### 5.2 UI 层：try-catch + Toast
+
+UI 层异步操作使用 try-catch，通过 `sonner` 的 `toast` 显示错误：
+
+```typescript
+import { toast } from 'sonner';
+
+const handleCopy = useCallback(async () => {
+  try {
+    await navigator.clipboard.writeText(value);
+    toast.success('复制成功');
+  } catch {
+    toast.error('复制失败');
+  }
+}, [value]);
+```
+
+### 5.3 Promise 异常隔离
+
+对不关心返回值的异步操作，使用 `void` + `.catch()` 隔离异常：
+
+```typescript
+// ✅ void + .catch 模式
+void storageUtil.set(THEME_MODE_KEY, next).catch((err) => {
+  console.error('[Theme Storage Error] Failed to persistent theme state:', err);
+});
+
+// ✅ async 函数调用 + .catch
+loadConfig().catch(console.error);
+```
+
+### 5.4 ErrorBoundary
+
+在应用顶层使用 `ErrorBoundary` 组件捕获子组件树异常：
+
+```typescript
+import ErrorBoundary from '@/components/ErrorBoundary';
+
+<ErrorBoundary>
+  <RouterContainer />
+</ErrorBoundary>
+```
+
+---
+
+## 6. 命名规范
+
+### 6.1 文件命名
+
+| 类型        | 命名模式                   | 示例                                                     |
+| ----------- | -------------------------- | -------------------------------------------------------- |
+| 页面目录    | PascalCase                 | `Timestamp/`, `Base64Converter/`, `StorageCleaner/`      |
+| 页面入口    | `index.tsx`                | `pages/Timestamp/index.tsx`                              |
+| 组件文件    | PascalCase `.tsx`          | `TopBar.tsx`, `LiveClock.tsx`, `ResultView.tsx`          |
+| 自定义 Hook | camelCase `.ts`            | `useTimestampConverter.ts`, `useStorageCleaner.ts`       |
+| 工具函数    | camelCase `.ts`            | `chromeStorage.ts`, `base64Converter.ts`, `clipboard.ts` |
+| 测试文件    | 与源文件同名 `.test.ts(x)` | `jwt.test.ts`, `SwitchButtonGroup.test.tsx`              |
+| 类型文件    | camelCase `.d.ts`          | `storage.d.ts`                                           |
+| 常量文件    | camelCase `.ts`            | `constants.ts`                                           |
+
+### 6.2 变量 / 函数命名
+
+```typescript
+// ✅ camelCase — 变量、函数、Hook
+const conversionPipeline = useMemo(...);
+const handleUseNow = useCallback(...);
+export function useTimestampConverter(): UseTimestampConverterReturn { ... }
+export function textToBase64(text: string): TextToBase64Result { ... }
+
+// ✅ PascalCase — 组件、类型、接口
+const LiveClock = React.memo(...);
+export interface GlobalSnackbarProps { ... }
+export type ThemeMode = 'light' | 'dark' | 'system';
+
+// ✅ SCREAMING_SNAKE_CASE — 常量
+const SEARCH_HISTORY_LIMIT = 10;
+const THEME_MODE_KEY = 'app/themeMode' as const;
+export const MAX_FILE_SIZE = 10 * 1024 * 1024;
+export const SUPPORTED_IMAGE_TYPES = [...] as const;
+
+// ✅ 布尔值 — is/has/should 前缀
+const isControlled = controlledValue !== undefined;
+const isDashboard = currentPage === 'dashboard';
+const hasError = true;
+```
+
+### 6.3 事件处理函数
+
+使用 `handle` 前缀命名组件内事件处理函数：
+
+```typescript
+const handleUseNow = useCallback((now: number) => { ... }, []);
+const handleSelectFeature = (feature: FeatureConfig) => { ... };
+const handleFileChange = useCallback((file: File) => { ... }, []);
+const handleClean = useCallback(async () => { ... }, []);
+```
+
+---
+
+## 7. 测试规范
+
+### 7.1 文件组织
+
+测试文件放在源代码同级的 `__tests__/` 目录下：
+
+```
+utils/__tests__/jwt.test.ts
+utils/__tests__/base64Converter.test.ts
+utils/__tests__/useStorageState.test.ts
+components/__tests__/SwitchButtonGroup.test.tsx
+components/__tests__/ErrorBoundary.test.tsx
+pages/Timestamp/__tests__/index.test.tsx
+```
+
+### 7.2 describe / it 命名
+
+`describe` 使用模块/函数名，`it` 使用中文描述行为（"应该..."）：
+
+```typescript
+// ✅ 中文 describe + 中文 it
+describe('textToBase64', () => {
+  it('应该编码 ASCII 文本', () => { ... });
+  it('应该编码中文文本', () => { ... });
+  it('应该编码空字符串', () => { ... });
+});
+
+// ✅ 中文 describe + 中文 it（组件测试）
+describe('SwitchButtonGroup 组件', () => {
+  it('应渲染所有选项按钮', () => { ... });
+  it('应高亮当前选中的按钮', () => { ... });
+  it('点击未选中按钮时应触发 onChange 并传入选中值', () => { ... });
+});
+```
+
+### 7.3 Mock 模式
+
+- 使用 `vi.mock()` 进行模块级 Mock
+- 使用 `vi.fn()` 进行函数级 Mock
+- 使用 `vi.useFakeTimers()` 控制时间
+- **避免重复 mock `vitest.setup.ts` 中已有的内容**（chrome API、i18n、matchMedia 等）
+
+```typescript
+// ✅ 模块级 Mock
+vi.mock('@/utils/chromeStorage', () => ({
+  storageUtil: {
+    get: vi.fn(),
+    set: vi.fn(() => Promise.resolve()),
+  },
+}));
+
+// ✅ 函数级 Mock + 断言
+const handleChange = vi.fn();
+render(<SwitchButtonGroup value="a" options={options} onChange={handleChange} />);
+fireEvent.click(screen.getByRole('button', { name: /选项B/i }));
+expect(handleChange).toHaveBeenCalledTimes(1);
+expect(handleChange).toHaveBeenCalledWith('b');
+
+// ✅ 定时器 Mock
+beforeEach(() => {
+  vi.useFakeTimers();
+  vi.clearAllMocks();
+});
+afterEach(() => {
+  vi.restoreAllMocks();
+  vi.useRealTimers();
+});
+```
+
+### 7.4 断言模式
+
+使用 Testing Library 的 DOM 查询 + Vitest 匹配器：
+
+```typescript
+// ✅ 语义化查询
+expect(screen.getByRole('button', { name: /选项A/i })).toBeInTheDocument();
+expect(screen.getByTestId('normal-content')).toHaveTextContent('正常内容');
+expect(screen.queryByText('糟糕，出了点问题')).not.toBeInTheDocument();
+
+// ✅ CSS 类断言
+expect(button).toHaveClass('bg-background', 'text-foreground', 'shadow-sm');
+
+// ✅ 异步断言
+await waitFor(() => {
+  expect(result.current[0]).toBe(false);
+  expect(result.current[2]).toBe(true);
+});
+
+// ✅ renderHook 测试自定义 Hook
+const { result } = renderHook(() => useStorageState('qrCode/urlExpanded', true));
+expect(result.current[0]).toBe(true);
+```
+
+---
+
+## 8. 自定义 Hook 规范
+
+### 8.1 命名和结构
+
+- 使用 `use` 前缀命名
+- 定义返回值接口类型
+- 添加 JSDoc 注释
+
+```typescript
+// ✅ 完整的 Hook 结构
+/**
+ * 自定义 Hook：处理右键菜单传递的数据
+ *
+ * @param options - 配置选项
+ * @example
+ * useContextMenuData({ featureKey: 'jwt', onData: handlePayload });
+ */
+export function useContextMenuData({ featureKey, onData }: UseContextMenuDataOptions): void {
+  const checkAndConsumeData = useCallback(async () => { ... }, [featureKey, onData]);
+  useEffect(() => { checkAndConsumeData(); }, [checkAndConsumeData]);
+}
+
+// ✅ 返回值接口定义
+export interface UseTimestampConverterReturn {
+  mode: 'ts2dt' | 'dt2ts';
+  input: string;
+  result: string;
+  error: string;
+  setMode: (mode: 'ts2dt' | 'dt2ts') => void;
+  setInput: (value: string) => void;
+  handleUseNow: (now: number) => void;
+}
+
+export function useTimestampConverter(): UseTimestampConverterReturn { ... }
+```
+
+### 8.2 Hook 存放位置
+
+- **全局通用 Hook**：放在 `utils/` 目录下
+- **页面专属 Hook**：与页面组件同目录
+
+```
+utils/useStorageState.ts          — Chrome Storage 状态持久化
+utils/useLazyTranslation.ts       — i18n 懒加载
+utils/useContextMenuData.ts       — 右键菜单数据
+utils/useDebounce.ts              — 防抖
+pages/Timestamp/useTimestampConverter.ts    — 页面级 Hook
+pages/StorageCleaner/useStorageCleaner.ts  — 页面级 Hook
+```
+

+### 9.1 翻译键格式
+
+- 命名空间：`common`（默认）、`features`
+- 翻译键格式：`namespace:key`（如 `features:timestamp.title`）
+- 语言：`zh`（默认）、`en`
+
+### 9.2 翻译文件结构
+
+```
+i18n/locales/{zh,en}/common.json           — 全局通用翻译
+i18n/locales/{zh,en}/features.json         — 功能模块标题和描述
+i18n/locales/{zh,en}/{功能名}.json         — 各功能独立翻译
+```
+
+### 9.3 使用方式
+
+```typescript
+// ✅ 页面组件 — 使用 useLazyTranslation
+import { useLazyTranslation } from '@/utils/useLazyTranslation';
+
+export default function Index() {
+  const { t } = useLazyTranslation('timestamp');
+  return <h1>{t('timestamp:title')}</h1>;
+}
+
+// ✅ 全局组件 — 使用 useTranslation
+import { useTranslation } from 'react-i18next';
+
+export function TopBar() {
+  const { t } = useTranslation(['common', 'features']);
+  return <span>{t('common:settings')}</span>;
+}
+```
+
+### 9.4 添加新翻译
+
+1. 在 `i18n/locales/{zh,en}/features.json` 添加功能标题和描述
+2. 创建 `i18n/locales/{zh,en}/{功能名}.json` 添加功能专属翻译
+3. 在 `utils/useLazyTranslation.ts` 的 `localeModules` 中注册新命名空间
+

+
+## 10. 存储规范
+
+### 10.1 StorageSchema
+
+所有 Chrome Storage 键必须在 `types/storage.d.ts` 的 `StorageSchema` 中声明：
+
+```typescript
+export interface StorageSchema {
+  'app/currentRoute': PageType;
+  'app/popupRoute': PageType;
+  'app/theme': string;
+  'app/themeMode': 'light' | 'dark' | 'system';
+  'storageCleaner/preferences': StorageCleanerPreferences;
+  // ...
+}
+```
+
+### 10.2 存储操作
+
+使用 `utils/chromeStorage.ts` 的类型安全封装：
+
+```typescript
+import { storageUtil } from '@/utils/chromeStorage';
+import type { StorageSchema } from '@/types/storage';
+
+// ✅ 读取
+const theme = await storageUtil.get('app/theme', 'default');
+
+// ✅ 写入
+await storageUtil.set('app/theme', 'dark');
+
+// ✅ 删除
+await storageUtil.remove('app/theme');
+```
+
+### 10.3 持久化状态 Hook
+
+使用 `useStorageState` 自动同步 Chrome Storage：
+
+```typescript
+import { useStorageState } from '@/utils/useStorageState';
+
+const [themeMode, setThemeMode, isInitialized] = useStorageState(
+  'app/themeMode',
+  'system',
+  isValidMode, // 可选的类型守卫
+);
+```
+
+---
+
+## 11. 文件组织
+
+### 11.1 页面组件结构
+
+```
+pages/FeatureName/
+├── index.tsx              # 页面 UI（纯展示，使用 shadcn/ui 组件）
+├── useFeatureName.ts      # 业务逻辑 Hook（状态管理 + 转换逻辑）
+├── constants.ts           # 常量定义（可选）

+├── ResultView.tsx         # 子组件（可选）
+└── __tests__/             # 测试文件
+    └── index.test.tsx
+```
+
+### 11.2 目录职责
+
+| 目录             | 职责                                                         |

+
+## 12. 代码风格
+
+### 12.1 Prettier 配置

+# Copilot 指令
+
+基于 WXT 框架的浏览器扩展项目（React 19 + TypeScript），为开发者和测试人员提供效率工具：时间戳转换、存储清理、JWT 解析、JSON 工具、二维码、Base64、Markdown 等。
+
+## 核心命令
+
+```bash
+npm run dev              # Chrome 开发模式（支持 HMR）
+npm run dev:firefox      # Firefox 开发模式
+npm run build            # Chrome 生产构建
+npm run build:firefox    # Firefox 生产构建
+npm run zip              # 打包 Chrome 扩展（.output/*.zip）
+npm run zip:firefox      # 打包 Firefox 扩展
+npm run lint             # ESLint 检查（--max-warnings=0）
+npm run typecheck        # TypeScript 类型检查（tsc --noEmit）
+npm run test             # 运行全部单元测试（vitest run）
+npm run test:watch       # Vitest 监视模式
+npm run test:coverage    # 带覆盖率的测试
+```
+
+运行单个测试文件：`npx vitest run path/to/file.test.ts`
+
+修改 `package.json` 后需运行 `npm install`（会自动触发 `postinstall` → `wxt prepare` 重新生成 `.wxt/` 类型声明）。
+
+## CI 流水线（GitHub Actions）
+
+严格顺序门控，任一步骤失败则终止：
+
+1. **setup** — 安装依赖，缓存 `node_modules`
+2. **lint**、**typecheck**、**test** — 三者并行运行，全部通过才继续
+3. **build** — Chrome + Firefox 矩阵构建（仅当步骤 2 全部通过时执行）
+
+Pre-commit 钩子（`.husky/pre-commit` → `lint-staged`）：
+
+1. 代码文件（`*.{ts,tsx,js,jsx,mjs}`）：运行 `eslint --fix --max-warnings=0`
+2. 同一代码文件：运行 `prettier --write`
+3. 其他文件（`*.{json,css,scss,md}`）：运行 `prettier --write`
+
+## 项目架构
+
+### 路由（不使用 React Router）
+
+路由完全通过 `config/features.tsx` 中的 `FEATURES` 数组管理。每个功能定义一个 `key`（类型为 `types/storage.d.ts` 中的 `PageType`）和三个懒加载组件，分别对应 `popup`、`sidepanel`、`tab` 三种渲染模式。`providers/RouterProvider.tsx` 中的 `RouterProvider` 根据存储状态渲染当前页面。
+
+存在三套独立的路由作用域：`app/popupRoute`、`app/sidepanelRoute`、`app/tabRoute`，各自维护独立的可见页面列表和页面排序。
+
+### 存储
+
+所有 Chrome Storage 键必须在 `types/storage.d.ts` 的 `StorageSchema` 中声明，键名使用 kebab-case 格式（如 `app/currentRoute`）。使用 `utils/chromeStorage.ts` 中的类型安全封装（`storageUtil.get/set/remove`）。
+
+Router 同时使用 `chrome.storage.local` 持久化和 `localStorage` 快照来消除首屏闪烁。
+
+### 扩展通信
+
+使用 `@webext-core/messaging`。通信协议在 `utils/messages.ts` 中通过 `ProtocolMap` 定义。使用该模块导出的 `sendMessage` / `onMessage`，不要直接使用原生 `chrome.runtime.sendMessage`。
+
+### 页面组件模式
+
+功能页面遵循 **UI + Hook 分离** 模式：
+
+```
+pages/FeatureName/
+├── index.tsx              # UI 组件（纯展示，使用 shadcn/ui 组件）
+├── useFeatureName.ts      # 业务逻辑 Hook（状态管理 + 转换逻辑）
+└── constants.ts           # 常量定义（可选）
+```
+
+- 页面组件调用 `useLazyTranslation('featureName')` 获取翻译函数
+- Hook 负责所有状态管理，通过返回值暴露给页面
+- 子组件可进一步拆分（如 `LiveClock.tsx`、`ResultView.tsx`）
+
+### 新功能开发清单
+
+1. 在 `types/storage.d.ts` 的 `PageType` 联合类型中添加新成员
+2. 在 `config/features.tsx` 的 `FEATURES` 数组中添加配置（key、翻译键、图标、三种渲染模式组件）
+3. 在 `pages/` 目录创建页面组件（懒加载）：
+   - `index.tsx` — 使用 `useLazyTranslation` 的 UI 组件
+   - `useFeatureName.ts` — 业务逻辑 Hook
+   - `constants.ts` — 常量（可选）
+4. 在 `i18n/locales/{zh,en}/features.json` 添加翻译（复杂功能可新建独立 JSON 文件）
+5. 如需新权限，更新 `wxt.config.ts` 的 `manifest.permissions`
+6. 添加对应的单元测试
+
+## 关键规范
+
+> 完整的代码编写规范详见 [CODING_STANDARDS.md](./CODING_STANDARDS.md)。
+
+### 浏览器 API
+
+始终使用 `wxt/browser` 导出的 `browser` 对象，而非原生 `chrome` API，以确保跨浏览器兼容性。
+
+### 路径别名
+
+`@/` 映射到项目根目录（已在 tsconfig 和 vitest.config 中配置）。跨目录导入使用 `@/` 绝对别名，同目录导入使用 `./` 相对路径。
+
+### UI 组件
+
+- 使用 `components/ui/` 下的 shadcn/ui 组件（button、dialog、select、input 等）
+- 图标：`lucide-react`
+- 样式：Tailwind CSS + `@/lib/utils` 中的 `cn()` 工具函数（clsx + tailwind-merge）
+- 主题：使用 shadcn/ui 语义化 token（`bg-background`、`text-foreground`、`border-border` 等），禁止硬编码颜色
+
+### 代码分割
+
+`wxt.config.ts` 通过 `manualChunksForHtmlOnly()` 自动分组 vendor 依赖（vendor-react、vendor-i18n、vendor-qr、vendor-dnd、vendor-markdown），无需手动配置。
+
+### 代码风格
+
+- 禁止使用 `any`（测试文件除外）
+- 未使用的变量/参数：使用 `_` 前缀（如 `_unused`）
+- Prettier：100 字符宽、单引号、尾逗号 all、LF 换行
+- ESLint 使用 `typescript-eslint` 的 `projectService: true`
+- 导出模式：页面组件 default export，工具函数/Hook 命名导出，UI 组件 forwardRef + 命名导出
+
+### 测试
+
+- 环境：jsdom
+- 全局变量：`vitest/globals`（describe、it、expect 等无需导入）
+- Setup 文件：`vitest.setup.ts` 自动 mock 以下内容：
+  - `chrome.*` / `browser.*` API（storage、tabs、runtime、cookies 等）
+  - `react-i18next`（返回 key 作为翻译）
+  - `@/utils/useLazyTranslation`（返回 `ns:key` 格式）
+  - `window.matchMedia`
+- 测试文件命名：`__tests__/*.test.{ts,tsx}` 或 `*.test.{ts,tsx}`
+- 使用 `vi.mock()` 进行模块级 mock；避免重复 mock `vitest.setup.ts` 中已有的内容
+- 测试工具：`@testing-library/react` + `@testing-library/user-event`
+
+### 国际化（i18n）
+
+- 命名空间：`common`（默认）、`features`
+- 翻译键格式：`namespace:key`（如 `features:timestamp.title`）
+- 语言：`zh`（默认）、`en`
+- 翻译文件：`i18n/locales/{zh,en}/{common,features}.json` + 各功能独立 JSON 文件
+- 使用 `useLazyTranslation` Hook 加载功能专属翻译
+- 回退策略：缺失的翻译键回退到 `zh`，若仍缺失则返回占位格式 `namespace:key`
+
+### WXT 生成文件
+
+- `.wxt/` 目录由 `postinstall`（`wxt prepare`）自动生成，包含 TypeScript 类型声明和扩展 tsconfig
+- 生产构建输出到 `.output/` 目录
+- `tsconfig.json` 继承自 `./.wxt/tsconfig.json`

 ## 验证流程
 
-CI 执行顺序: `lint → typecheck → test → build` (build 依赖前三者)。
+CI 步骤（严格顺序，任一步骤失败则停止并标记 CI 失败）：
 
-Pre-commit hook (lint-staged) 顺序:
+1. `setup`（安装依赖、`wxt prepare`）
+2. 并行运行 `lint`、`typecheck`、`test`（三者全部通过才继续）
+3. `build`（仅当步骤 2 全部成功时执行）
 
-1. `prettier --write`
-2. `eslint --fix --max-warnings=0`
-3. `tsc --noEmit`
+Pre-commit hook（`.husky/pre-commit` 调用 `lint-staged`，任一步骤返回非零则终止提交）：
 
-提交前确保三者通过。
+1. 代码文件 (`*.{ts,tsx,js,jsx,mjs}`)：运行 `eslint --fix --max-warnings=0 --no-warn-ignored`；若失败则终止并报告错误
+2. 同一代码文件：运行 `prettier --write`
+3. 其他文件 (`*.{json,css,scss,md}`)：运行 `prettier --write`
+
+## WXT 生成文件
+
+- `.wxt/` 目录由 `postinstall` 自动执行 `wxt prepare` 生成，包含 TypeScript 类型声明和扩展的 tsconfig。
+- 生产构建输出到 `.output/` 目录。
+- `tsconfig.json` 继承自 `./.wxt/tsconfig.json`。

+### 页面组件模式
+
+典型功能页面遵循 **UI + Hook 分离** 模式：
+
+```
+pages/FeatureName/
+├── index.tsx              # 页面 UI（纯展示，使用 shadcn/ui 组件）
+├── useFeatureName.ts      # 业务逻辑 Hook（状态管理 + 转换逻辑）
+└── constants.ts           # 常量定义
+```
+
+- 页面组件调用 `useLazyTranslation('featureName')` 获取翻译函数
+- Hook 负责所有状态管理和业务逻辑，通过返回值暴露给页面
+- 子组件可进一步拆分（如 `LiveClock.tsx`、`ResultView.tsx`）
+
 ## 关键架构决策
 
-**路由**: 不使用 React Router。通过 `config/features.tsx` 的 `FEATURES` 数组管理，`RouterProvider` 根据 `PageType` 渲染对应组件。
+**路由**: 不使用 React Router。通过 `config/features.tsx` 的 `FEATURES` 数组管理，`RouterProvider` 根据 `PageType`
+渲染对应组件。支持三种渲染模式：popup（弹窗）、sidepanel（侧边栏）和 browser-tab（浏览器新标签页，通过 `open_in_tab` 打开）。
+每种模式有独立的路由和可见页面配置（`app/popupRoute`、`app/sidepanelRoute`、`app/tabRoute` 等）。
 
-**存储**: 所有 Chrome Storage 键必须在 `types/storage.d.ts` 的 `StorageSchema` 中定义。使用 `utils/chromeStorage.ts` 及其 Hook。
+**存储**: 所有 Chrome Storage 键必须在 `types/storage.d.ts` 的 `StorageSchema` 中定义，键名使用 kebab-case 格式（如 `app/currentRoute`）。
+使用 `utils/chromeStorage.ts` 及其 Hook。Router 同时使用 `chrome.storage.local` 和 `localStorage` 做快照以消除首屏闪烁。
+修改 StorageSchema 时，必须在 `utils/chromeStorage.ts` 添加版本迁移函数，并在测试中覆盖迁移场景。
 
 **通信**: 使用 `@webext-core/messaging`，协议定义在 `utils/messages.ts`。
 
 **路径别名**: `@/` 映射到项目根目录 (已在 tsconfig 和 vitest.config 中配置)。
 
+**浏览器兼容**: 优先使用 `wxt/browser` 导出的 `browser` 对象，而非原生 `chrome` API。
+
+**代码分割**: `wxt.config.ts` 通过 `manualChunksForHtmlOnly()` 自动分组依赖（vendor-react、vendor-i18n、vendor-qr 等），无需手动配置。
+
 ## 测试环境
 
 - 环境: jsdom
 - 全局变量: `vitest/globals` (describe, it, expect 等无需导入)
 - Setup 文件: `vitest.setup.ts` 自动 mock:
-  - `chrome.*` API (storage, tabs, runtime, cookies 等)
+  - `chrome.*` / `browser.*` API (storage, tabs, runtime, cookies 等)
   - `react-i18next` (返回 key 作为翻译)
+  - `@/utils/useLazyTranslation` (返回 `ns:key` 格式翻译)
   - `window.matchMedia`
 - 测试文件命名: `__tests__/*.test.{ts,tsx}` 或 `*.test.{ts,tsx}`
+- Mock 模式: 使用 `vi.mock()` 进行模块级 mock，避免在测试文件中重复 mock 代码
+- 测试工具: `@testing-library/react` + `@testing-library/user-event` 进行组件测试
 
 ## i18n
 
 - 命名空间: `common` (默认), `features`
 - 翻译键格式: `namespace:key` (如 `features:timestamp.title`)
 - 语言: `zh` (默认), `en`
-- 添加新翻译: 编辑 `i18n/locales/{zh,en}/{common,features}.json`
+- 翻译文件结构:
+  - `i18n/locales/{zh,en}/common.json` - 全局通用翻译
+  - `i18n/locales/{zh,en}/features.json` - 功能模块标题和描述
+  - `i18n/locales/{zh,en}/{功能名}.json` - 各功能独立翻译（如 timestamp.json, storageCleaner.json 等）
+- 添加新翻译: 编辑 `i18n/locales/{zh,en}/{common,features}.json` 及对应功能独立 JSON
+- 使用 `useLazyTranslation` hook 加载功能独立翻译，返回 `ns:key` 格式
+- 回退策略: 当翻译 key 在目标语言缺失时，回退到默认语言 `zh`；若默认语言也缺失，返回占位格式 `namespace:key` 并在开发模式下记录 warning

-# 为懒加载页面组件添加独立 ErrorBoundary 保护 — 设计文档
-
-- 日期：2026-05-13
-- 范围：popup / sidepanel / tab / options 入口下的页面错误隔离
-
-## 背景与目标
-
-当前应用通过 `config/features.tsx` 中的 `React.lazy()` 懒加载所有页面组件。`RouterContainer` 使用 `Suspense` 包裹动态组件，而错误边界仅在外层 `entrypoints/popup/App.tsx`、`entrypoints/sidepanel/App.tsx` 中包裹 `RouterContainer`、以及 `entrypoints/options/App.tsx` 顶层。
-
-问题：单个懒加载页面在加载或渲染时一旦抛错，错误会冒泡到全局 `ErrorBoundary`，触发全屏错误 UI，整个路由容器和 TopBar 一起被替换。用户必须刷新页面才能继续使用其他工具，体验受损。
-
-目标：将错误影响范围限制在当前页面区域；其他页面、TopBar、导航、Snackbar 不受影响；用户可在错误状态下切换到其他工具或重试当前页。
-
-## 设计概要
-
-新增 `PageErrorBoundary` 组件，专门用于页面级错误隔离，在 `RouterContainer` 的 `Suspense` 内层使用；`options/App.tsx` 也替换为同款页面级边界。现有全局 `ErrorBoundary` 保留作为兜底，覆盖 TopBar / Snackbar / RouterProvider 等同级组件。
-
-## 组件设计
-
-### `components/PageErrorBoundary.tsx`（新增）
-
-复用现有 `ErrorBoundary` 的错误捕获机制（`getDerivedStateFromError` + `componentDidCatch`），但具备以下差异：
-
-- **轻量内嵌 UI**：使用 `Paper` + 居中文本，去除全屏 `Container` + `mt:8` 布局，适配 popup 400×600 与 sidepanel 等窄屏环境。结构：
-  - 图标 (`ErrorOutlineIcon`)
-  - 标题："该页面加载失败"
-  - 副标题："页面在加载或渲染时遇到错误，您可以重试或切换到其他工具。"
-  - 折叠错误信息块（沿用现有错误展示样式，使用 monospace、可滚动）
-  - 主操作按钮："重试"（`RefreshIcon`）—— 重置内部 state，让子树重新挂载
-- **`resetKey` prop**：可选；当 `resetKey` 在 `componentDidUpdate` 中变化时，自动重置 `hasError` / `error`，无需用户手动操作
-- **`componentDidCatch`**：仍使用 `console.error('Uncaught error in page:', error, errorInfo)` 输出，不引入额外上报
-
-接口：
-```ts
-interface PageErrorBoundaryProps {
-  children: ReactNode;
-  resetKey?: string | number; // 变化时自动重置
-}
-```
-
-### `components/ErrorBoundary.tsx`（不变）
-
-保留作为全局兜底。负责捕获 TopBar、SnackbarProvider、RouterProvider 等同级组件中可能出现的错误，沿用全屏 `Container` 样式与"刷新应用"操作。
-
-## 集成点
-
-### `components/RouterContainer.tsx`（修改）
-
-在 `Suspense` 内层插入 `PageErrorBoundary`，传入 `resetKey={currentPage}`：
-
-```tsx
-<Suspense fallback={<Spinner />}>
-  <PageErrorBoundary resetKey={currentPage}>
-    {Component && <Component />}
-  </PageErrorBoundary>
-</Suspense>
-```
-
-说明：
-- `PageErrorBoundary` 置于 `Suspense` 内部，可同时捕获懒加载 chunk 加载失败（异步异常）与页面渲染期同步错误
-- `resetKey={currentPage}` 使页面切换时自动清除错误状态，无需用户干预
-- 保留外层 `Box key={currentPage}` 与动画 className，不改变页面切换语义
-
-### `entrypoints/options/App.tsx`（修改）
-
-将顶层 `<ErrorBoundary>` 替换为 `<PageErrorBoundary>`。options 是单页应用，统一使用页面级错误卡片即可。
-
-### `entrypoints/popup/App.tsx`、`entrypoints/sidepanel/App.tsx`（不变）
-
-保留外层 `<ErrorBoundary>` 包裹 `<RouterContainer />`，作为同级组件（TopBar 等）的兜底。`PageErrorBoundary` 与全局 `ErrorBoundary` 各司其职：
-
-- 页面级（`PageErrorBoundary`）：捕获懒加载页面内部错误，隔离影响范围，仅替换页面区域
-- 全局（`ErrorBoundary`）：捕获 RouterContainer 自身、TopBar、Snackbar 等组件错误，作为最后兜底
-
-## 数据流 / 错误处理
-
-### 捕获路径
-- 懒加载 chunk 加载失败（网络 / CSP / chunk 缺失） → `Suspense` 内部 promise reject → `PageErrorBoundary` 捕获
-- 页面渲染期同步错误（组件抛错、null 引用等） → `PageErrorBoundary` 捕获
-- 事件回调或 Promise 中的异步错误 → React 错误边界不捕获（固有行为，本次不处理）
-
-### 恢复路径
-- **页面切换自动重置**：用户从错误页切换到其他页面 → `currentPage` 变化 → `resetKey` 变化 → `PageErrorBoundary.componentDidUpdate` 重置 → 新页面正常渲染
-- **当前页重试**：用户点击"重试" → 内部 state 重置 → 子树重新挂载 → React 重新触发 `lazy()` 加载（懒加载失败时也会重新发起 `import()`）
-- **持续错误**：若 `lazy()` chunk 始终无法加载（例如永久 404），重试会再次显示错误卡片；用户可切换到其他页面继续使用其他工具
-
-### 日志
-沿用 `console.error`；不引入 Sentry / 外部上报。
-
-## 测试策略
-
-### 新增 `components/__tests__/PageErrorBoundary.test.tsx`
-
-1. 正常渲染：子组件正常渲染时，输出原始 children
-2. 同步错误捕获：子组件抛错时，显示错误卡片（标题"该页面加载失败"、错误信息）
-3. 重试按钮恢复：错误状态下，将 children 替换为正常组件，点击"重试"按钮，重置状态并显示正常内容
-4. `resetKey` 变化自动重置：错误状态下 `resetKey` 变化时，自动清空错误并渲染新 children
-5. `resetKey` 不变保持错误：children 变化但 `resetKey` 未变化时，保持错误状态（避免误重置）
-6. 错误信息显示：错误的 `toString()` 内容能在 UI 中可见
-
-### 新增 `components/__tests__/RouterContainer.test.tsx`
-
-- 通过 mock `useRouter` 与 `FEATURES`，注入一个会抛错的懒加载组件，验证 `PageErrorBoundary` 捕获错误且 TopBar / 父容器 DOM 仍存在
-- 切换 `currentPage`（重新触发 hook 返回值）后验证错误自动清除、新页面正常渲染
-
-### 不变
-- `components/__tests__/ErrorBoundary.test.tsx` 不需改动（全局边界行为未变）
-
-### 风格
-遵循现有 `ErrorBoundary.test.tsx` 模式：`vi.spyOn(console, 'error')` 抑制噪声 + `@testing-library/react` 的 `render` + `screen.getByText` 断言。
-
-## 文件清单
-
-**新增：**
-- `components/PageErrorBoundary.tsx`
-- `components/__tests__/PageErrorBoundary.test.tsx`
-- `components/__tests__/RouterContainer.test.tsx`
-
-**修改：**
-- `components/RouterContainer.tsx` — 在 `Suspense` 内层包裹 `PageErrorBoundary resetKey={currentPage}`
-- `entrypoints/options/App.tsx` — 将 `<ErrorBoundary>` 替换为 `<PageErrorBoundary>`
-
-**不变：**
-- `components/ErrorBoundary.tsx`
-- `components/__tests__/ErrorBoundary.test.tsx`
-- `entrypoints/popup/App.tsx`、`entrypoints/sidepanel/App.tsx`
-- `config/features.tsx`
-
-## 验收标准
-
-1. 单页面在懒加载或渲染时抛错，仅当前页面区域显示错误卡片，TopBar 与导航仍可点击
-2. 在错误状态下切换到其他工具，新页面能正常加载与显示
-3. 点击错误卡片中的"重试"按钮，子树重新挂载并重新触发懒加载
-4. 全局 `ErrorBoundary` 仍能捕获 TopBar / Snackbar 等同级组件的错误
-5. 所有新增测试通过；现有 `ErrorBoundary` 测试不受影响；`npm run compile`、`npm run lint`、`npm run test` 均通过

+
+i18next 初始化配置：
+
+- 同步加载 `common` 和 `features` 核心命名空间
+- 自定义 `chromeStorage` 语言检测器，从 Chrome Storage 读取语言偏好
+- `normalizeLanguage()` 将任意语言标识归一化为 `zh` 或 `en`
+- 语言变更时同步更新 Day.js 本地化和 localStorage 快照
+
+## 翻译键格式
+
+- 命名空间：`common`（默认）、`features`、各功能独立命名空间
+- 键格式：`namespace:key`（如 `features:timestamp.title`、`timestamp:unitMs`）
+
+## 使用方式
+
+```tsx
+// 页面组件 — 懒加载翻译
+import { useLazyTranslation } from '@/utils/useLazyTranslation';
+const { t } = useLazyTranslation('timestamp');
+t('timestamp:title');
+
+// 全局组件 — 直接使用
+import { useTranslation } from 'react-i18next';
+const { t } = useTranslation(['common', 'features']);
+t('common:settings');
+```
+
+## 添加新翻译
+
+1. 在 `locales/{zh,en}/features.json` 添加功能标题和描述
+2. 创建 `locales/{zh,en}/{功能名}.json` 添加功能专属翻译
+3. 在 `utils/useLazyTranslation.ts` 的 `localeModules` 中注册新命名空间

+## 文件说明
+
+| 文件                    | 用途                   |

+| `RouterProvider.tsx`    | 路由 Context Provider  |
+| `ThemeModeProvider.tsx` | 主题模式 Provider      |
+
+## AppRoot.tsx
+
+应用根 Provider 组合器，按顺序包裹：
+
+```
+React.StrictMode
+  └── ThemeModeProvider
+        └── RouterProvider
+              └── children
+```
+
+## RouterProvider.tsx
+
+路由 Context Provider，管理：
+
+- **当前页面**：`currentPage`（`PageType`）
+- **可见页面列表**：`visiblePages`
+- **页面排序**：`pageOrder`
+- **加载状态**：`isLoaded`
+
+核心特性：
+
+- 通过 `chrome.storage` 持久化路由状态
+- 使用 `localStorage` 快照实现首屏 0 闪烁
+- 支持 popup/sidepanel/tab 三种入口的独立路由同步（通过 `syncKey`、`visiblePagesKey`、`pageOrderKey` 配置）
+- 处理右键菜单待处理数据的路由跳转
+- 监听 `chrome.storage.onChanged` 实现跨端同步
+
+导出：
+
+- `RouterProvider` 组件
+- `useRouter()` Hook — 获取 `currentPage`、`visiblePages`、`pageOrder`、`navigateTo`、`goBack` 等
+
+## ThemeModeProvider.tsx
+
+主题模式 Provider，管理：
+
+- **主题模式**：`light` / `dark` / `system`
+- **解析后的主题**：`resolvedTheme`（`light` / `dark`）
+
+核心特性：
+
+- 使用 `localStorage` 快照实现首屏 0 闪烁
+- 监听系统级暗色模式变化（`matchMedia`）
+- 通过 `chrome.storage` 跨端同步主题偏好
+- 自动在 `document.documentElement` 上切换 `dark` class
+
+导出：
+
+- `ThemeModeProvider` 组件
+- `useThemeMode()` Hook — 获取 `themeMode`、`resolvedTheme`、`setThemeMode`

+
+- **Tailwind 指令**：`@tailwind base/components/utilities`
+- **shadcn/ui CSS 变量**：定义 `--background`、`--primary`、`--destructive`、`--card`、`--muted`、`--accent`、`--border`、`--ring` 等语义化颜色变量
+- **主题色值**：`:root`（亮色）和 `.dark`（暗色）两套完整的颜色定义
+- **圆角变量**：`--radius` 定义全局圆角大小
+
+## 修改注意事项
+
+- 修改 CSS 变量会影响所有使用 shadcn/ui 语义化 token 的组件
+- 新增颜色变量需同时在 `:root` 和 `.dark` 中定义
+- 避免在组件中硬编码颜色值，应使用 CSS 变量或 Tailwind 的语义化类名
