# 宿主机 Nginx：443 终止 TLS，反代到本机 Docker web（127.0.0.1:5173）
# web 容器内 nginx 已把 /api/、/ai/、/gateway/ 转发到 gateway。
#
# 占位符（由 scripts/lib-aijz-deploy.sh 替换）：
#   __DOMAIN__       站点域名
#   __WEB_PORT__     宿主机 web 映射端口（默认 5173）
#   __VERIFY_ROOT__  域名验证文件目录（项目 verify-root/）
#
# 手动部署：
#   1. 证书放到 /etc/ssl/aijianzhan/__DOMAIN__/{fullchain.pem,privkey.pem}
#   2. sudo cp 生成后的 conf 到 /etc/nginx/conf.d/
#   3. sudo nginx -t && sudo systemctl reload nginx
