+### 配置容器时区

+本项目支持通过 `docker-compose.yml` 的环境变量 `TZ` 配置容器运行时区（需要使用有效的 IANA 时区名，例如 `Asia/Shanghai`、`UTC`、`America/New_York`）。

+- 临时指定（当前终端会话生效）：

 - 默认会以 `--reload` 模式启动，监听本地 8080 端口，可在浏览器访问 `http://localhost:8080`。
 - 通过 `./app/config.json` 保存的 Plex 配置信息会在主机和容器间共享，便于调试时保留登录 token 等数据。
 - 如需自定义端口或其他参数，可在 `docker-compose.yml` 中调整。
