+| API      | 8000       | `API_PORT`       | 8000           | 8001              | FastAPI 服务，Nginx 反代后端       |
+| Web      | 80         | `WEB_PORT`       | 3001           | 3002              | Nginx + 前端静态文件               |

+
+### 补充说明
+- API 容器内部固定监听 8000（`API_HOST=0.0.0.0`，`API_PORT=8000`）
+- Web 容器内部 Nginx 固定监听 80
+- 所有端口均绑定 `127.0.0.1`，不直接暴露公网，由前置 Nginx/CDN 转发

+
+## 六、命名规范
+
+### 推荐命名格式
+
+统一使用 `{服务/用途}_PORT` 格式：
+
