/* ---- 管理后台相关入口：默认隐藏，确认管理员后显示 ----
 *
 * 文档站是预生成的静态 HTML，导航结构对所有访问者一致，服务端无法按角色裁剪
 * 同一份文件。管理后台章节本身已由反向代理强制鉴权（非管理员访问
 * /handbook/<版本>/admin/** 返回 404，见 deploy/nginx.conf）；这里只做界面层的
 * 「不把入口摆在免费用户眼前」。
 *
 * 采用「默认隐藏 + 管理员显形」而非「默认显示 + 免费用户隐藏」：
 * 隐藏规则写在 CSS 中，免费用户与未登录访客不会看到入口闪现；
 * 管理员方向的一瞬延迟是无害的。
 *
 * 判定：docs/javascripts/admin-nav.js 请求 /api/v1/auth/me，
 * 确认为管理员时给 <html> 加上 .wi-is-admin。
 *
 * 选择器全部使用「匹配不到就不隐藏」，因此即使结构与预期不符
 * （或浏览器不支持 :has()），也只会退化为「入口仍可见」，不会破坏导航；
 * 真正的访问控制始终由反向代理负责。
