# 门店检测工作台 —— 服务器 / Linux 启动脚本（非交互，适合 systemd、nohup、docker）
#
# 用法：
#   ./start.sh                  # 默认端口 8787，开放局域网
#   ./start.sh 9000             # 指定端口
#   ./start.sh --local          # 只允许本机访问（放在 nginx 后面时用）
#   PORT=9000 ./start.sh        # 也可以用环境变量
#
# 建议放在 systemd 里跑，见 deploy/门店检测工作台.service
