/* =====================================================================
   星空主题 · 登录页样式（Starfield UI）
   ---------------------------------------------------------------------
   作用范围：仅登录页 .login 容器，后台其它页面完全不受影响
   接入方式：nginx 在 SPA 入口 HTML 的 </head> 前注入本文件，
             见 /www/server/panel/vhost/nginx/ttgadget.tech.conf 中的 sub_filter
   还原方式：删除 nginx 中的 sub_filter 一行即可（应用本体未被改动）
   设计要点：深空底色 + 四层视差星层 + 偶发流星 + 高对比玻璃卡片，
             文字与边框保持锐利（“超级清晰”），不使用大面积模糊
