   站点前台样式（原生 CSS，零依赖 / 零构建）
   —— PC 门户（/site、/donation、/site-upload）

   ⚠️ 本文件同时被 layouts/h5.php 在 h5.css **之前**引入：
      H5 侧会用自己的 :root 覆盖 --brand/--text/--border，
      并且 .h5-body 自带白底，所以这里改主题**不会**影响移动端。
      但反过来要注意：不要删掉 h5.css 会用到的变量名
      （--brand / --border / --text / --card …）。

   设计基准（取自 donation.php / site-upload.php 的实测值，保持全站一致）：
      品牌红 #C81623（渐变 #B91C1C → #DC2626）
      页面底色 #F7F8FA，卡片白底 / 1px #E8EAED 边 / 圆角 12px
      正文 #1F2328，次要 #6B7280，极浅 #9CA3AF
