 ### 9.1 翻译键格式
 
-- 命名空间：`common`（默认）、`features`
+- 使用 Chrome 扩展标准的 `chrome.i18n`，通过 `src/utils/chromeI18n.ts` 暴露 `useI18n`
-- 翻译键格式：`namespace:key`（如 `features:timestamp.title`）
+- 翻译 key 存放在 `public/_locales/zh_CN/messages.json`
-- 语言：`zh`（默认）、`en`
+- 直接 key：`t('dashboard_title')` → 查找 `dashboard_title`
+- 命名空间兼容写法：`t('common:buttons.search')` → 查找 `common_buttons_search`
+- 命名空间参数：`useI18n(['common', 'features'])` 会尝试 `common_key`、`features_key`
 
 ### 9.2 翻译文件结构
 
 ```
-i18n/locales/{zh,en}/common.json           — 全局通用翻译
+public/_locales/zh_CN/messages.json        — Chrome 扩展默认语言包

 ```
 
 ### 9.3 使用方式
 
 ```typescript
-// ✅ 页面组件 — 使用 useLazyTranslation
+// ✅ 页面组件 / 子组件 — 使用 useI18n
-import { useLazyTranslation } from '@/utils/useLazyTranslation';
+import { useI18n } from '@/utils/chromeI18n';

+| `business.ts`  | 业务数据生成器（订单号、价格、日期、状态等）   |
+| `technical.ts` | 技术数据生成器（UUID、IPv4、URL）              |
+| `basic.ts`     | 基础类型生成器（整数、浮点数、布尔值、字符串） |
+| `types.ts`     | 生成器库内部类型与通用选项                     |
+
+使用示例：
+
+```typescript
+import { getGeneratorById, searchGenerators } from '@/lib/generators';
+
+const generator = getGeneratorById('chineseName');
+const value = generator?.generate({});
+const matched = searchGenerators('uuid');
+```
+
+约束：
+
+- 新增生成器必须实现 `GeneratorDefinition`，并加入所属分类文件的导出列表。
+- 需要唯一值或大批量稳定输出时，优先实现 `generateAtIndex(params, index)`。
+- 新增分类时同步更新 `generatorCategories`，并确保 `GeneratorSelector` 能展示该分类。

 ## 使用约定
 
 - 工具函数使用**命名导出**（`export function xxx()`）
-- 工具函数**不抛异常**，返回包含 `hasError` 和 `error` 字段的结果对象
+- 工具层不直接展示 Toast；可恢复错误返回可判断结果，需要抛出的解析/转换错误由页面 Hook 或 UI 层捕获
 - Hook 使用 `use` 前缀命名，定义返回值接口类型
 - 存储操作使用 `chromeStorage.ts` 的 `storageUtil` 封装，不要直接调用 `chrome.storage`
 - 消息通信使用 `messages.ts` 的 `sendMessage`/`onMessage`，不要使用原生 `chrome.runtime.sendMessage`
