   - 去掉重新匹配按钮，改为返回按钮

2. 修复所有卡片对齐和宽度问题
   - 目录页附录卡片居中
   - 首页阅读进度卡片满宽度
   - 我的页面菜单卡片对齐
   - 推广中心分享卡片统一宽度

3. 修复目录页图标和文字对齐
   - section-icon固定40rpx宽高
   - section-title与图标垂直居中

4. 更新真实完整文章标题(62篇)
   - 从book目录读取真实markdown文件名
   - 替换之前的简化标题

5. 新增文章数据API
   - /api/db/chapters - 获取完整书籍结构
   - 支持按ID获取单篇文章内容
