 | 变量 | 默认值 | 说明 |
 |------|--------|------|
+| `BASE_DIR` | 当前工作目录 | 项目根目录（用于定位 data/pic/web/public） |
+| `HOST` | 127.0.0.1 | 服务器监听地址 |
 | `PORT` | 8080 | 服务器监听端口 |

 ## 注意事项

 1. 数据文件永久保留，不会自动清理
 2. 页面使用 Playwright 获取完整渲染后的内容
-3. 服务器默认绑定到 localhost，如需外网访问请修改 server.js 中的监听地址
+3. 默认监听地址为 127.0.0.1，可通过环境变量 HOST 修改
