   独立样式表：不依赖 Tailwind，也不依赖后台样式。

   视觉口径（两处对齐）：
   1) 顶部导航 —— 与官网首页 index.php 的 <nav> 完全一致：
      fixed / 透明→滚动变白模糊 / max-w-7xl(1280) / h-16 / logo h-10 /
      链接 px-4 py-2 text-sm 灰→hover 蓝底蓝字 / ≤1023px 汉堡+全屏菜单。
   2) 主体 —— 与后台「资讯中心」门户页（backend/views/article/portal.php）一致：
      1280 居中 + 左 200px 分类白卡 + 右侧内容白卡（标题左侧 3px 竖条、
      列表行 = 圆点 + 标题 + 右侧更新时间、底部翻页器）。
