/* ============================================================

   经核查，所有 [data-skeleton-auto] 包裹的页面均为服务端渲染（SSR），
   真实内容（主机卡/订单/价格表等）已直接写入 HTML。
   原机制把真实内容用内联 display:none 藏起、先显示灰块骨架，
   等同"遮住已存在的内容"，制造空与等待感。
   此处用 !important 覆盖内联与非 important 样式：真实内容首屏即显示、
   灰块永不出现，仅保留 main.php 注入的顶栏进度条 #ssBar。
   注：若未来新增"真实需要客户端拉取数据"的 [data-skeleton-auto] 页，
   须改为局部启用骨架，而非沿用此全局覆盖。
