+# 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，详见 [CODING_STANDARDS.md § 11](./CODING_STANDARDS.md#11-页面开发规范)：
+
+```
+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 `useI18n('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），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`

-**测试技术栈：**
+运行单个测试: `npx vitest run path/to/file.test.ts`
 
-- Vitest - 测试框架
-- @testing-library/react - React 组件测试
-- @testing-library/user-event v13 - 用户交互模拟（注意：v13 不支持 setup()，使用 fireEvent）
-- jsdom - 浏览器环境模拟
+## 验证流程
 
-### 依赖与准备
+CI 步骤（严格顺序，任一步骤失败则停止并标记 CI 失败）：
 
-- `npm install` - 安装依赖
-- `postinstall` 会自动运行 `wxt prepare` 准备开发环境
-- `prepare` 钩子会初始化 Husky Git 钩子
+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）
 
-## 项目架构
+Pre-commit hook（`.husky/pre-commit` 调用 `lint-staged`，任一步骤返回非零则终止提交）：
 
-### 技术栈
+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`
 
-- **框架**: WXT (Web Extension Toolkit) - 浏览器扩展开发框架
-- **前端**: React 19 + TypeScript
-- **UI 库**: Material UI (MUI)
-- **状态管理**: React Hooks
-- **路由**: React Router DOM
+## WXT 生成文件
 
-### 目录结构
+- `.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`。

-### 核心功能实现
+### 页面组件模式
 
-#### 1. 时间戳转换工具
+典型功能页面遵循 **UI + Hook 分离** 模式。详见 [CODING_STANDARDS.md § 11](./.github/CODING_STANDARDS.md#11-页面开发规范)。
 
-- 位置: `components/` 目录下的时间戳相关组件
-- 依赖: dayjs 库进行日期处理
-- 功能: 支持日期与时间戳的双向转换，支持多种格式
-
-#### 2. 通信系统
-
-- 位置: `utils/messages.tsx`
-- 机制: 使用 `@webext-core/messaging` 库实现
-- 通信通道: 后台脚本 ↔ 内容脚本 ↔ 弹窗
-
-#### 3. 数据存储
-
-- Chrome Storage API: `utils/chromeStorage.ts` (用于配置等小数据)
-
-### 关键配置文件
-
-#### wxt.config.ts
-
-- 配置 WXT 框架参数
-- 启用 React 模块
-- 配置浏览器扩展权限
-- Vite 构建配置（使用 Terser 压缩，强制 ASCII 编码）
-
-#### manifest 权限
-
-```typescript
-permissions: [
-  'storage',           // 存储权限
-  'unlimitedStorage',  // 无限制存储
-  'clipboardWrite',    // 剪贴板写入
-  'activeTab',         // 当前标签页
-  'scripting',         // 脚本注入
-  'tabs',              // 标签页管理
-  'debugger',          // 调试器
-],
-host_permissions: ['<all_urls>']  // 访问所有网站
+```
+src/pages/FeatureName/
+├── index.tsx              # 页面 UI（纯展示，仅负责渲染布局）
+├── useFeatureName.ts      # 业务逻辑 Hook（状态管理 + 转换逻辑）
+├── constants.ts           # 常量定义（可选，≥3 个常量时创建）
+└── __tests__/
+    └── index.test.tsx
 ```
 
-## 开发注意事项
+- 页面入口组件统一命名为 `Index`，通过 `export default function Index()` 导出
+- Hook 负责所有状态管理和业务逻辑，通过返回值暴露给页面
+- 子组件可以独立调用 `useI18n` 等全局 Hook
+- 当 `index.tsx` 超过 150 行时，必须拆分为 UI + Hook 模式
+- 复杂页面可增加 `contexts/`、`hooks/`、`components/` 子目录
 
-### 扩展入口点
+## 关键架构决策
 
-- **后台脚本**: `entrypoints/background.ts` - 处理扩展生命周期和后台任务
-- **内容脚本**: `entrypoints/content.ts` - 注入到网页中，处理 DOM 交互
-- **弹窗**: `entrypoints/popup/main.tsx` - 用户点击扩展图标时显示
+**路由**: 不使用 React Router。通过 `src/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）。
 
-### 浏览器兼容性
+**存储**: 所有 Chrome Storage 键必须在 `src/types/storage.d.ts` 的 `StorageSchema` 中定义，键名使用 kebab-case 格式（如 `app/currentRoute`）。
+使用 `src/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 `src/utils/chromeStorage.ts` 添加版本迁移函数，并在测试中覆盖迁移场景。
 
-- 支持 Chrome 和 Firefox 浏览器
-- 使用 WXT 框架抽象浏览器差异
+**通信**: 使用 `@webext-core/messaging`，协议定义在 `src/utils/messages.ts`。
 
-### 代码质量
+**路径别名**: `@/` 映射到项目根目录 (已在 tsconfig 和 vitest.config 中配置)。
 
-- 使用 ESLint 进行代码检查
-- Husky 用于 Git 钩子管理
-- Lint-staged 确保暂存文件符合规范
+**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-qr、vendor-dnd 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.*` / `browser.*` API (storage, tabs, runtime, cookies 等)
+  - `@/utils/chromeI18n` (从 `public/_locales/zh/messages.json` 加载真实翻译)
+  - `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 (chrome.i18n)
+
+项目使用 Chrome 扩展标准的 `chrome.i18n` API 进行本地化，通过 `src/utils/chromeI18n.ts` 提供类型安全的 React Hook 包装。
+
+- **翻译文件**: `public/_locales/{zh,en}/messages.json`（Chrome 扩展标准格式）
+- **默认语言**: `zh`（在 `wxt.config.ts` 的 `manifest.default_locale` 中配置）
+- **使用方式**: `import { useI18n } from '@/utils/chromeI18n'`
+- **翻译键格式**:
+  - 直接 key: `t('dashboard_title')` → 查找 `dashboard_title`
+  - 命名空间格式（兼容旧用法）: `t('common:buttons.search')` → 查找 `common_buttons_search`
+  - 带命名空间参数: `useI18n(['common', 'features'])`，会自动尝试 `common_key`、`features_key`
+- **占位符支持**: `t('router_notFoundDescription', { entryPointType: 'popup' })`
+- **Hook 返回值**: `{ t, i18n: { language, changeLanguage }, isLoaded }`
+- **回退策略**: 当翻译 key 未命中时，返回 key 本身（开发模式下在控制台记录 warning）
+- **限制**: `chrome.i18n` 无法动态切换语言，语言跟随浏览器设置，切换后需刷新页面
+
+## 新功能开发清单
+
+1. 在 `src/types/storage.d.ts` 添加 `PageType` 联合类型
+2. 在 `src/config/features.tsx` 的 `FEATURES` 数组添加配置（指定 key、翻译键、图标、三种渲染模式的组件）
+3. 在 `src/pages/` 创建页面组件 (懒加载)：
+   - `index.tsx` — UI 组件，使用 `useI18n` 获取翻译
+   - `useFeatureName.ts` — 业务逻辑 Hook
+   - `constants.ts` — 常量（可选）
+4. 在 `public/_locales/zh/messages.json`（及 `en/messages.json`）添加翻译
+5. 如需新权限，更新 `wxt.config.ts` 的 `manifest.permissions`
+6. 添加对应的单元测试
+
+## 代码规范
+
+- 禁止使用 `any` (测试文件除外)
+- 未使用变量/参数: 使用 `_` 前缀 (如 `_unused`)
+- 样式: 使用 Tailwind CSS + shadcn/ui (通过 `className` 和 `cn()` 工具)
+- UI 组件: 优先使用 `src/components/ui/` 下的 shadcn/ui 组件 (button, dialog, select 等)
+- 图标: 使用 `lucide-react` 图标库
+- 格式: Prettier (`.prettierrc`: 100 字符宽, 单引号, 尾逗号 all, LF 换行)
+- ESLint 使用 `typescript-eslint` 的 `projectService: true`（无需手动维护 project 路径）
+
+## 关键外部库（非显而易见的）
+
+- `@webext-core/messaging` — 扩展消息通信
+- `@dnd-kit` — 拖拽排序（用于页面顺序管理）
+- `qrious` + `qr-scanner` — 二维码生成与解析
+- `dayjs` — 日期处理（时间戳转换）
+- `sonner` — Toast 通知（替代传统 snackbar）

-## 3. 开发规范与风格约定
-
-### 3.1 UI 设计语言
-
-- **极简主义 (Minimalist)**: 参考 Vercel 和 Apple 的设计语言。
-- **MUI 定制**:
-  - 严禁使用 MUI 默认的粗犷边框和深重阴影。
-  - 必须通过 `sx` 属性进行深度样式定制，去除 `notchedOutline`。
-  - 偏好使用 `grey.50` 背景区分层级，使用 `borderRadius: 4` (大圆角)。
-  - 交互反馈：禁用波纹效果 (`disableRipple`)，移除默认阴影 (`disableElevation`)。
-- **布局**: 优先使用 `Stack` 和 `Box` 进行布局，确保自上而下的操作流顺畅。
-
-### 3.2 技术选型惯例
-
-- **日期转换**: 必须通过 `utils/dayjs.ts` 导出的实例进行，确保时区处理一致。
-- **状态管理**: 优先使用 React 原生 `useState` 和 `useMemo`。
-- **存储**: 使用 `utils/chromeStorage.ts` 封装的类型安全接口。
-- **通信**: 使用 `@webext-core/messaging` 进行 background 和 popup 之间的消息传递。
-
-## 4. 关键指令
-
-### 4.1 开发与调试
-
-- `npm run dev`: 启动 Chrome 扩展开发模式。
-- `npm run dev:firefox`: 启动 Firefox 扩展开发模式。
-
-### 4.2 构建与检查
-
-- `npm run build`: 构建生产版本。
-- `npm run compile`: TypeScript 类型检查。
-- `npm run lint`: ESLint 代码风格检查。
-
-## 5. 权限与清单 (Manifest)
-
-- **核心权限**: `storage`, `unlimitedStorage`, `clipboardWrite`, `scripting`, `tabs`, `debugger`, `cookies`。
-- **宿主权限**: `<all_urls>` (用于在所有页面注入 content 脚本)。
-- **构建细节**: 生产环境构建使用 `terser` 压缩，并强制 `ascii_only` 以确保字符兼容性。
-
-## 6. 维护者提示
-
-在修改 `TimestampPage.tsx` 等核心页面时，应保持**逻辑层**（基于 dayjs 的转换算法）与**渲染层**（JSX/MUI 样式）的严格分离。

+
+## 1. 设计原则
+
+### 1.1 核心定位
+
+Testing Tools 是一款**浏览器扩展开发者工具集**，视觉风格遵循：
+
+- **专业克制** — 低饱和度色彩，避免视觉噪音
+- **信息密度优先** — 紧凑布局，在 400×600px 的 popup 空间内高效展示
+- **开发者友好** — 等宽字体用于代码/数据，清晰的信息层级
+- **一致性至上** — 所有页面、组件遵循同一套视觉语言
+
+### 1.2 设计关键词
+
+```
+简洁 · 现代 · 功能导向 · 低对比度 · 微圆角 · 微妙阴影
+```
+
+### 1.3 与 shadcn/ui 的关系
+
+本项目以 shadcn/ui 为底座，所有基础组件（Button、Input、Select 等）均来自或对齐 shadcn/ui 的默认样式。业务组件在此基础上扩展，**不得破坏底层设计语言的统一性**。
+
+---
+
+## 2. 色彩系统
+
+### 2.1 CSS 变量定义
+
+所有色彩通过 CSS 自定义属性（HSL 格式）管理，定义于 `src/index.css`：
+
+#### 亮色模式 (`:root`)
+
+| 变量名                     | HSL 值              | 用途          | 近似色    |
+| -------------------------- | ------------------- | ------------- | --------- |
+| `--background`             | `0 0% 100%`         | 页面背景      | `#ffffff` |
+| `--foreground`             | `222.2 84% 4.9%`    | 主文字        | `#020617` |
+| `--card`                   | `0 0% 100%`         | 卡片背景      | `#ffffff` |
+| `--card-foreground`        | `222.2 84% 4.9%`    | 卡片文字      | `#020617` |
+| `--popover`                | `0 0% 100%`         | 浮层背景      | `#ffffff` |
+| `--popover-foreground`     | `222.2 84% 4.9%`    | 浮层文字      | `#020617` |
+| `--primary`                | `222.2 47.4% 11.2%` | 主按钮/强调   | `#0f172a` |
+| `--primary-foreground`     | `210 40% 98%`       | 主按钮文字    | `#f8fafc` |
+| `--secondary`              | `210 40% 96.1%`     | 次级背景      | `#f1f5f9` |
+| `--secondary-foreground`   | `222.2 47.4% 11.2%` | 次级文字      | `#0f172a` |
+| `--muted`                  | `210 40% 96.1%`     | 静音/禁用背景 | `#f1f5f9` |
+| `--muted-foreground`       | `215.4 16.3% 46.9%` | 次要文字      | `#64748b` |
+| `--accent`                 | `210 40% 96.1%`     | 悬停高亮      | `#f1f5f9` |
+| `--accent-foreground`      | `222.2 47.4% 11.2%` | 悬停文字      | `#0f172a` |
+| `--destructive`            | `0 84.2% 60.2%`     | 错误/删除     | `#ef4444` |
+| `--destructive-foreground` | `210 40% 98%`       | 错误文字      | `#f8fafc` |
+| `--border`                 | `214.3 31.8% 91.4%` | 边框          | `#e2e8f0` |
+| `--input`                  | `214.3 31.8% 91.4%` | 输入框边框    | `#e2e8f0` |
+| `--ring`                   | `222.2 84% 4.9%`    | 焦点环        | `#020617` |
+| `--radius`                 | `0.5rem`            | 全局圆角      | `8px`     |
+
+#### 暗色模式 (`.dark`)
+
+暗色模式下所有变量自动反转，保持对比度关系：
+
+| 变量名                 | HSL 值              | 近似色    |
+| ---------------------- | ------------------- | --------- |
+| `--background`         | `222.2 84% 4.9%`    | `#020617` |
+| `--foreground`         | `210 40% 98%`       | `#f8fafc` |
+| `--primary`            | `210 40% 98%`       | `#f8fafc` |
+| `--primary-foreground` | `222.2 47.4% 11.2%` | `#0f172a` |
+| `--secondary`          | `217.2 32.6% 17.5%` | `#1e293b` |
+| `--muted`              | `217.2 32.6% 17.5%` | `#1e293b` |
+| `--border`             | `217.2 32.6% 17.5%` | `#1e293b` |
+
+### 2.2 使用规范
+
+```tsx
+// ✅ 正确：使用 CSS 变量
+<div className="bg-background text-foreground border-border">
+
+// ✅ 正确：使用语义化色彩名
+<Button className="bg-primary text-primary-foreground">
+<span className="text-muted-foreground">
+
+// ❌ 错误：硬编码颜色值
+<div className="bg-white text-black">
+<div className="bg-[#f1f5f9]">
+```
+
+### 2.3 语义化色彩使用场景
+
+| 色彩                       | 场景                             |

+| `card` + `card-foreground` | 卡片容器及其内容                 |
+| `primary`                  | 主按钮、选中状态、关键操作       |
+| `secondary`                | 次级按钮、工具栏背景、标签页背景 |
+| `destructive`              | 错误提示、删除操作、验证失败     |
+| `accent`                   | 悬停背景、下拉选中项             |

+
+## 7. 交互与动效
+
+### 7.1 过渡规范
+
+| 属性                | 值         | 场景                          |
+| ------------------- | ---------- | ----------------------------- |
+| `transition-colors` | 150ms ease | 色彩变化（悬停、焦点）        |
+| `transition-all`    | 150ms ease | 综合变化（SwitchButtonGroup） |
+| `duration-200`      | 200ms      | 复制按钮状态切换              |
+
+### 7.2 焦点状态
+
+所有可交互元素必须有可见的焦点指示器：
+
+```tsx
+// 标准焦点环
+focus-visible:outline-none focus-visible:ring-2 focus-visible:ring-ring focus-visible:ring-offset-2
+
+// 紧凑焦点环（图标按钮）
+focus-visible:outline-none focus-visible:ring-1 focus-visible:ring-ring
+
+// 输入框焦点
+focus-visible:outline-none focus-visible:ring-2 focus-visible:ring-ring focus-visible:ring-offset-2
+```
+
+### 7.3 悬停状态
+
+```tsx
+// 按钮悬停
+hover:bg-accent hover:text-accent-foreground
+
+// 卡片悬停
+hover:bg-muted/30 hover:border-[rgba(var(--tool-color),0.45)]
+
+// 链接/文字悬停
+hover:text-foreground hover:underline
+```
+
+### 7.4 动画规范
+
+使用 `tailwindcss-animate` 提供的动画：
+
+```tsx
+// 淡入
+animate-in fade-in duration-150
+
+// 淡入 + 缩放（SwitchButtonGroup 选中项）
+animate-in fade-in-50 zoom-in-95 duration-150
+
+// 从顶部滑入（下拉菜单）
+animate-in fade-in slide-in-from-top-2 duration-150
+
+// 错误提示出现
+animate-in fade-in slide-in-from-top-1 duration-150
+
+// 骨架屏脉冲
+animate-pulse
+```
+
+### 7.5 禁用状态
+
+```tsx
+// 统一禁用样式
+disabled:pointer-events-none disabled:opacity-50
+```
+
+---
+
+## 8. 暗色模式
+
+### 8.1 实现方式
+
+通过 `darkMode: 'class'`（Tailwind 配置）+ `.dark` 类切换：
+
+```tsx
+// ThemeModeProvider 自动处理
+document.documentElement.classList.toggle('dark', resolvedMode === 'dark');
+```
+
+### 8.2 暗色模式下的特殊处理
+
+```tsx
+// 彩色阴影增强（暗色模式下阴影需要更高透明度）
+shadow-[0_8px_24px_-8px_rgba(var(--tool-color),0.14)]
+dark:shadow-[0_8px_30px_-10px_rgba(var(--tool-color),0.25)]
+
+// 图标容器背景增强
+bg-[rgba(var(--tool-color),0.08)]
+dark:bg-[rgba(var(--tool-color),0.12)]
+
+// 成功状态文字调整
+text-emerald-600 dark:text-emerald-400
+```
+
+### 8.3 暗色模式色彩映射原则
+
+| 亮色             | 暗色             | 说明                            |
+| ---------------- | ---------------- | ------------------------------- |
+| 纯白背景         | 深蓝黑背景       | 避免纯黑 `#000`，使用 `#020617` |
+| 浅灰背景         | 深灰背景         | 保持层次关系                    |
+| 深文字           | 浅文字           | 反转对比度                      |
+| 彩色阴影低透明度 | 彩色阴影高透明度 | 暗色需要更强视觉反馈            |
+
+---
+
+## 9. 工具色彩标识
+
+### 9.1 色板定义
+
+每个工具分配一个主题色，定义于 `src/config/features.tsx`：
+
+```ts
+const PALETTE_COLORS: Record<PaletteColorKey, string> = {
+  primary: '13, 148, 136', // teal (#0d9488)
+  success: '22, 163, 74', // green (#16a34a)
+  warning: '217, 119, 6', // amber (#d97706)
+  error: '220, 38, 38', // red (#dc2626)
+  secondary: '147, 51, 232', // purple (#9333e8)
+  info: '37, 99, 235', // blue (#2563eb)
+};
+```
+
+### 9.2 工具色彩分配
+
+| 工具        | 色彩键      | 色值   |
+| ----------- | ----------- | ------ |
+| 时间戳转换  | `primary`   | Teal   |
+| 存储清理    | `warning`   | Amber  |
+| 二维码工具  | `success`   | Green  |
+| 文本统计    | `secondary` | Purple |
+| JWT 解析    | `info`      | Blue   |
+| JSON 对比   | `primary`   | Teal   |
+| Base64 转换 | `info`      | Blue   |
+| 右键还原    | `success`   | Green  |
+
+### 9.3 工具色彩使用规范
+
+```tsx
+// 1. 通过 style 注入 CSS 变量
+<div style={{ ['--tool-color' as string]: rgbValues }}>
+
+// 2. 图标容器背景（低透明度）
+bg-[rgba(var(--tool-color),0.08)]
+dark:bg-[rgba(var(--tool-color),0.12)]
+
+// 3. 图标颜色
+ text-[rgb(var(--tool-color))]
+
+// 4. 悬停边框
+hover:border-[rgba(var(--tool-color),0.45)]
+
+// 5. 悬停阴影
+hover:shadow-[0_8px_24px_-8px_rgba(var(--tool-color),0.14)]
+
+// 6. 箭头悬停色
+group-hover:text-[rgb(var(--tool-color))]
+```
+
+**注意**：工具色彩仅用于**标识和装饰**，不得用于功能性色彩（如成功/错误状态）。
+
+---
+
+## 10. 代码规范
+
+### 10.1 Tailwind 类名组织顺序
+
+使用 `cn()` 工具函数（`clsx` + `tailwind-merge`）组合类名，按以下顺序排列：
+
+```tsx
+className={cn(
+  // 1. 布局（display, position, flex, grid）
+  'flex items-center justify-between',
+  // 2. 尺寸（width, height, padding, margin）
+  'w-full h-10 px-4',
+  // 3. 外观（background, border, shadow, rounded）
+  'rounded-md border border-input bg-background shadow-sm',
+  // 4. 文字（color, font, text-align）
+  'text-sm font-medium text-foreground',
+  // 5. 交互（hover, focus, disabled, cursor）
+  'hover:bg-accent focus-visible:ring-2 disabled:opacity-50',
+  // 6. 动画（transition, animate）
+  'transition-colors duration-150',
+  // 7. 条件类
+  isActive && 'bg-primary text-primary-foreground',
+  // 8. 外部传入
+  className,
+)}
+```
+
+### 10.2 颜色使用检查清单
+
+- [ ] 所有颜色使用 CSS 变量（`bg-background` 而非 `bg-white`）
+- [ ] 边框使用 `border-border` 及其透明度变体
+- [ ] 文字层级使用 `foreground` → `muted-foreground` → `muted-foreground/60`
+- [ ] 错误状态使用 `destructive` 系列
+- [ ] 工具色彩仅用于装饰性元素
+
+### 10.3 组件文件组织
+
+```

+        <h4 className="font-bold text-sm tracking-tight">{t('newTool:title')}</h4>
+      </div>
+    </div>
+  );
+}
+```
+
+---
+
+## 11. 反模式清单
+
+以下模式**禁止**在项目中使用：
+
+### 11.1 色彩反模式
+
+```tsx
+// ❌ 硬编码颜色
+<div className="bg-white text-black">
+<div className="bg-gray-100">
+<div className="text-gray-500">
+
+// ❌ 使用非语义化 Tailwind 颜色
+<div className="bg-slate-50">
+<div className="text-zinc-400">
+
+// ✅ 使用 CSS 变量
+<div className="bg-background text-foreground">
+<div className="bg-muted text-muted-foreground">
+```
+
+### 11.2 布局反模式
+
+```tsx
+// ❌ 固定高度导致内容截断
+<div className="h-[200px]">
+
+// ✅ 使用 min-height 或自适应
+<div className="min-h-[200px]">
+<div className="h-auto">
+
+// ❌ 使用 margin 做组件间距
+<div className="mb-4">
+
+// ✅ 使用 gap
+<div className="flex flex-col gap-4">
+```
+
+### 11.3 组件反模式
+
+```tsx
+// ❌ 修改 shadcn/ui 基础组件样式
+// 如需修改，通过 className 覆盖或创建包装组件
+
+// ❌ 内联样式用于颜色（工具色彩除外）
+<div style={{ backgroundColor: '#f1f5f9' }}>
+
+// ❌ 混合使用不同圆角体系
+<Button className="rounded-lg">  // Button 应为 rounded-md
+
+// ❌ 忽略焦点状态
+<button className="...">  // 缺少 focus-visible 样式
+```
+
+### 11.4 暗色模式反模式
+
+```tsx
+// ❌ 仅适配部分元素
+<div className="bg-white text-black dark:bg-gray-900 dark:text-white">
+
+// ✅ 使用 CSS 变量自动适配
+<div className="bg-background text-foreground">
+
+// ❌ 暗色模式下使用不合适的透明度
+<div className="bg-black/5 dark:bg-white/5">  // 对比度不足
+
+// ✅ 使用语义化变量
+<div className="bg-muted">
+```

-# Storage Cleaner Implementation Plan
-
-> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
-
-**Goal:** Add a storage cleaner feature to the browser extension popup that allows users to clear localStorage, sessionStorage, IndexedDB, Cookies, Cache Storage, andress Workers for the current page.
-
-**Architecture:** Add new StorageCleanerPage component with tab switching in the popup, using chrome.cookies API for cookies and script injection for other storage types. User preferences are persisted using Chrome Storage.
-
-**Tech Stack:** React 19 + TypeScript, Material UI, Chrome Extension APIs

-
-## Testing Checklist
-
-After implementation, verify:
-
-- [ ] Tab switching works between timestamp and storage cleaner
-- [ ] Current domain displays correctly
-- [ ] All storage type checkboxes toggle correctly
-- [ ] Auto refresh checkbox persists across sessions
-- [ ] Clear confirmation dialog appears
-- [ ] Confirmation dialog shows selected storage types
-- [ ] localStorage clears successfully
-- [ ] sessionStorage clears successfully
-- [ ] IndexedDB clears successfully (or shows error if unavailable)
-- [ ] Cookies clear successfully
-- [ ] Clear httponly and secure cookies
-- [ ] Cache Storage clears successfully
-- [ ] Service Workers unregister successfully
-- [ ] Result message displays correctly
-- [ ] Empty state shows friendly message
-- [ ] Auto refresh works
-- [ ] Manual refresh button appears when auto-refresh is off
-- [ ] Restricted pages show error message
-- [ ] Snackbar notifications appear correctly
-- [ ] Test on localhost
-
----
-
-## Rollback Plan
-
-If issues occur during testing:
-
-1. Revert to before implementation:
-
-   ```bash
-   git reset --hard <commit-before-start>
-   ```
-
-2. Or revert specific files:
-   ```bash
-   git checkout HEAD -- types/storage.d.ts wxt.config.ts utils/storageCleaner.ts entrypoints/popup/App.tsx entrypoints/popup/pages/StorageCleanerPage.tsx
-   ```
-
----
-
-## Notes
-
-- The popup closes automatically when the page is refreshed - this is expected behavior
-- IndexedDB.databases() may not be available in all browser versions; the fallback handles this
-- Chrome Cookies API requires explicit permission, which is added to the manifest
-- User preferences are persisted using the existing chromeStorage.ts utility

-# 存储清理功能设计文档
-
-## 概述
-
-为浏览器扩展添加一个存储清理功能，允许用户快速清理当前页面的各种存储数据，包括 localStorage、sessionStorage、IndexedDB、Cookies、Cache Storage 和 Service Workers。
-
-## 目标
-
-- 提供便捷的页面存储清理功能
-- 支持多种存储类型清理
-- 提供清理结果反馈
-- 支持清理后自动刷新页面
-
-## 架构设计
-
-### 组件结构
-
-```
-entrypoints/popup/pages/
-├── TimestampPage.tsx        (现有：时间戳转换页面)
-└── StorageCleanerPage.tsx    (新增：存储清理页面)
-```
-
-### 页面布局
-
-在弹窗中添加标签页切换功能，用户可以在时间戳转换和存储清理之间切换。
-
-**路由实现方案：**
-
-使用简单的状态管理进行页面切换：
-
-```typescript
-// App.tsx
-type PageType = 'timestamp' | 'storageCleaner';
-
-function App() {
-  const [currentPage, setCurrentPage] = useState<PageType>('timestamp');
-
-  return (
-    <div className="app">
-      <Box sx={{ display: 'flex', justifyContent: 'center', mb: 2 }}>
-        <Button
-          variant={currentPage === 'timestamp' ? 'contained' : 'outlined'}
-          onClick={() => setCurrentPage('timestamp')}
-        >
-          时间戳
-        </Button>
-        <Button
-          variant={currentPage === 'storageCleaner' ? 'contained' : 'outlined'}
-          onClick={() => setCurrentPage('storageCleaner')}
-          sx={{ ml: 1 }}
-        >
-          存储清理
-        </Button>
-      </Box>
-      {currentPage === 'timestamp' && <TimestampPage />}
-      {currentPage === 'storageCleaner' && <StorageCleanerPage />}
-    </div>
-  );
-}
-```
-
-## 用户界面设计
-
-### 页面组成
-
-1. **头部区域**
-   - 标题："存储清理"
-   - 当前域名显示（自动从活动标签页获取）
-
-2. **存储类型选择区域**
-   - 勾选框：localStorage
-   - 勾选框：sessionStorage
-   - 勾选框：IndexedDB
-   - 勾选框：Cookies
-   - 勾选框：Cache Storage
-   - 勾选框：Service Workers
-
-3. **自动刷新选项**
-   - 复选框：清理完成后自动刷新页面（默认勾选）
-
-4. **操作区域**
-   - 清理按钮
-
-5. **结果显示区域**
-   - 清理成功/失败提示
-   - 清理详情统计（如："清理了 5 个 localStorage, 3 个 cookies"）
-   - 刷新页面按钮（当未勾选自动刷新时显示）
-
-## 技术实现细节
-
-### 获取当前标签页域名
-
-使用 Chrome Tabs API 获取当前活动标签页，并过滤受限页面：
-
-```typescript
-const [tab] = await chrome.tabs.query({ active: true, currentWindow: true });
-
-// 检查受限页面
-const restrictedProtocols = [
-  'chrome:',
-  'chrome-extension:',
-  'about:',
-  'edge:',
-  'view-source:',
-  'file:',
-  'data:',
-];
-
-if (!tab?.url || restrictedProtocols.some((p) => tab.url!.startsWith(p))) {
-  throw new Error('存储清理功能不支持此页面');
-}
-
-const domain = new URL(tab.url).hostname;
-```
-
-### 清理 Cookies（使用 chrome.cookies API）
-
-在扩展环境中直接执行，不需要注入页面：
-
-```typescript
-const cookies = await chrome.cookies.getAll({ url: tab.url });
-let count = 0;
-for (const cookie of cookies) {
-  await chrome.cookies.remove({
-    url: tab.url,
-    name: cookie.name,
-    storeId: cookie.storeId,
-  });
-  count++;
-}
-```
-
-### 注入脚本清理其他存储
-
-使用 `chrome.scripting.executeScript` 注入清理脚本：
-
-```typescript
-const result = await chrome.scripting.executeScript({
-  target: { tabId: tab.id },
-  func: () => {
-    // 清理逻辑在页面上下文中执行
-  },
-});
-```
-
-需要注入到页面执行的存储清理逻辑：
-
-#### 清理 localStorage
-
-```javascript
-const count = localStorage.length;
-localStorage.clear();
-return count;
-```
-
-#### 清理 sessionStorage
-
-```javascript
-const count = sessionStorage.length;
-sessionStorage.clear();
-return count;
-```
-
-#### 清理 IndexedDB
-
-```javascript
-// 检查 indexedDB.databases 方法是否可用
-if (typeof indexedDB.databases === 'function') {
-  const databases = await indexedDB.databases();
-  let count = 0;
-  for (const db of databases) {
-    const deleteReq = indexedDB.deleteDatabase(db.name);
-    deleteReq.onblocked = () => {
-      console.warn('IndexedDB delete blocked:', db.name);
-    };
-    await new Promise((resolve, reject) => {
-      deleteReq.onsuccess = resolve;
-      deleteReq.onerror = reject;
-    });
-    count++;
-  }
-  return count;
-}
-// 降级方案：由于无法获取所有数据库名称，提示返回特殊值表示需要手动操作
-return { error: 'databases_api_unavailable' };
-```
-
-#### 清理 Cache Storage
-
-```javascript
-if ('caches' in window) {
-  const cacheNames = await caches.keys();
-  for (const name of cacheNames) {
-    await caches.delete(name);
-  }
-  return cacheNames.length;
-}
-return 0;
-```
-
-#### 注销 Service Workers
-
-```javascript
-if ('serviceWorker' in navigator) {
-  const registrations = await navigator.serviceWorker.getRegistrations();
-  let count = 0;
-  for (const registration of registrations) {
-    await registration.unregister();
-    count++;
-  }
-  return count;
-}
-return 0;
-```
-
-### 数据流
-
-1. 页面加载时获取当前标签页 URL 并显示域名
-2. 检查是否为受限页面（chrome://, about:// 等），如果是则显示错误提示
-3. 用户勾选要清理的存储类型
-4. 用户选择是否自动刷新页面
-5. 用户点击清理按钮
-6. 弹出确认对话框询问用户确认
-7. 确认后执行清理：
-   - 如果选择 Cookies：直接使用 chrome.cookies API 删除
-   - 其他存储类型：向页面注入清理脚本
-8. 收集所有清理结果并统计
-9. 显示清理结果
-10. 如果勾选"自动刷新"或用户点击"刷新页面"按钮，执行页面刷新
-
-**注意：** 当触发页面刷新时，popup 会自动关闭。需要在刷新前显示提示信息。
-
-### 页面刷新
-
-```typescript
-// 显示刷新提示
-setRefreshing(true);
-setTimeout(async () => {
-  await chrome.tabs.reload(tab.id);
-}, 1500); // 1.5秒延迟让用户看到提示信息
-```
-
-### 空状态处理
-
-当所有存储类型清理返回 0 时，显示友好的提示：
-
-```
-该页面没有可清理的存储数据
-```
-
-## 错误处理
-
-| 错误场景                        | 处理方式                                 |
-| ------------------------------- | ---------------------------------------- |
-| 无法获取当前标签页              | 显示错误提示："无法获取当前标签页"       |
-| 受限页面（chrome://, about://） | 显示错误提示："存储清理功能不支持此页面" |
-| 无法访问页面 URL                | 显示错误提示："无法访问此页面"           |
-| IndexedDB onblocked             | 显示警告但继续执行其他清理               |
-| IndexedDB.databases 不可用      | 使用降级方案或提示用户手动清除           |
-| 清理失败                        | 显示具体错误信息                         |
-| Cookies 删除失败                | 记录错误，显示清理失败提示               |
-| 无权限                          | 提示用户刷新扩展或检查权限               |
-| 脚本注入失败                    | 显示错误提示："无法注入清理脚本"         |
-
-**Popup 生命周期说明：**
-
-- Popup 在页面失去焦点时会关闭
-- 刷新页面后 Popup 会自动关闭
-- 需要在刷新前显示提示："页面即将刷新，Popup 将关闭"
-
-## 用户偏好持久化
-
-使用现有的 `chromeStorage.ts` 工具保存用户偏好：
-
-```typescript
-// 保存用户偏好
-await storageUtil.set('storageCleaner/preferences', {
-  autoRefresh: true, // 默认勾选自动刷新
-  selectedTypes: {
-    // 可以保存用户上次选择的存储类型
-    localStorage: true,
-    sessionStorage: true,
-    indexedDB: true,
-    cookies: true,
-    cacheStorage: true,
-    serviceWorkers: true,
-  },
-});
-
-// 读取用户偏好
-const preferences = await storageUtil.get('storageCleaner/preferences', {
-  autoRefresh: true,
-  selectedTypes: {
-    localStorage: true,
-    sessionStorage: true,
-    indexedDB: true,
-    cookies: true,
-    cacheStorage: true,
-    serviceWorkers: true,
-  },
-});
-```
-
-## 权限需求
-
-需要在 manifest 中添加 `cookies` 权限：
-
-```typescript
-permissions: [
-  'storage',
-  'unlimitedStorage',
-  'clipboardWrite',
-  'activeTab',
-  'scripting',
-  'tabs',
-  'debugger',
-  'cookies', // 新增
-],
-```
-
-## TypeScript 类型定义
-
-在现有 `types/storage.d.ts` 中添加存储清理相关的类型：
-
-```typescript
-export interface StorageSchema {
-  'app/lastRoute': string;
-  'app/theme': string;
-  'storageCleaner/preferences': StorageCleanerPreferences;
-}
-
-export interface StorageCleanerPreferences {
-  autoRefresh: boolean;
-  selectedTypes: StorageCleanerOptions;
-}
-
-export interface StorageCleanerOptions {
-  localStorage: boolean;
-  sessionStorage: boolean;
-  indexedDB: boolean;
-  cookies: boolean;
-  cacheStorage: boolean;
-  serviceWorkers: boolean;
-}
-
-export type StorageCleanResult =
-  | {
-      success: true;
-      count: number;
-    }
-  | {
-      success: false;
-      error: string;
-    };
-
-export interface CleaningResult {
-  success: boolean;
-  error?: string;
-  localStorage?: StorageCleanResult;
-  sessionStorage?: StorageCleanResult;
-  indexedDB?: StorageCleanResult;
-  cookies?: StorageCleanResult;
-  cacheStorage?: StorageCleanResult;
-  serviceWorkers?: StorageCleanResult;
-}
-```
-
-## 测试计划
-
-1. 测试各种存储类型的单独清理
-2. 测试同时清理多种存储类型
-3. 测试自动刷新功能
-4. 测试手动刷新按钮
-5. 测试无存储数据时的清理（显示空状态提示）
-6. 测试无法访问页面的错误处理
-7. 测试受限页面（chrome://, about://, file://, data://）
-8. 测试 IndexedDB onblocked 场景
-9. 测试 httponly 和 secure cookies 清理
-10. 测试本地开发环境（localhost）
-11. 测试用户偏好持久化
-
-## 后续优化
-
-- 显示清理前的存储使用情况
-- 支持批量清理多个标签页
-- 支持自定义域名清理

+源码目录，存放全局样式定义。
+
+## 文件说明
+
+| 文件        | 用途              |
+| ----------- | ----------------- |
+| `index.css` | 全局 CSS 入口文件 |
+
+## index.css
+
+全局样式入口，包含：
+
+- **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
