+## 📋 功能清单
+
+- ✅ **公告列表**：从API获取公告，支持Mock/Production双模式
+- ✅ **频道筛选**：全部/系统公告/开发动态/团队消息，支持Hash路由
+- ✅ **骨架屏**：数据加载中显示动画占位，加载后平滑淡出
+- ✅ **离线降级**：断网时自动读取缓存，网络恢复后实时更新
+- ✅ **暗色主题**：跟随系统自动切换深色/浅色模式
+- ✅ **响应式设计**：适配桌面、平板、手机
+- ✅ **跨浏览器**：支持 Chrome / Edge / Firefox
+- ✅ **错误处理**：友好的错误提示 + 重试按钮
+

+
+## 🔧 环境配置
+
+配置文件：`js/config.js`
+
+```javascript
+// 环境开关：'mock' 或 'production'
+env: 'mock',  // 🟡 当前为Mock模式，待后端就绪后改为production
+
+// API地址（production模式使用）
+apiBaseUrl: 'https://api.example.com/v1',  // 待替换为真实地址
