# 宿主机 Nginx：443 终止 TLS
# - /api/、/ai/、/gateway/ → 本机 gateway（127.0.0.1:8180），避免经 web 容器 DNS 偶发 502
# - 静态页与其它路径 → web（127.0.0.1:5173）

# 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）
#   __GATEWAY_PORT__   宿主机 gateway 映射端口（默认 8180）
#   __VERIFY_ROOT__    域名验证文件目录（项目 verify-root/）
