# Admin Web (SPA) —— 子路径部署在 /admin/ 下(构建 base=/admin/,见 admin-web/vite.config.ts)。
#
# 2026-09-18 修正:此处原为 `alias /usr/share/nginx/html/;`,而本容器是 nginx:alpine
# 纯净镜像 —— 那个目录里只有镜像自带的欢迎页,并没有管理端产物。结果是访问 /admin/
# 返回 200 + nginx 欢迎页,属于"假成功",比 404 更难被发现(页面能打开,但不是管理端)。
# 真正的产物在 admin-web 容器内,故改为代理到 upstream。
#
# 代理**不剥离** /admin 前缀:管理端构建 base 为 /admin/,其 index.html 引用的资源
# 本身就以 /admin/ 开头,由 admin-web 容器内的 nginx(admin-web/nginx-admin.conf)
# 统一处理这个前缀,三处入口(生产 / 本地整套栈 / staging 直连)因此形态一致。
#
# 暴露面提醒:管理端登录页不应无条件对公网开放。当前依赖外层防火墙/WAF 控制;
# 若需在 nginx 层收敛,在此 location 内加 allow/deny 白名单(运营办公网段 + VPN)。
