   ★ 下面的数值不是「看着像」，是 2026-10-03 用无头浏览器把参考站渲染后的
     真实类名与 computed style 逐项量出来的，改之前别凭感觉改：
       容器 1180（跟本站 .wrap 一致，不能改成 1280，否则和本站导航/页脚错位）
       侧栏 208px（w-52） 卡片间距 20px（gap-5） 封面高 176px（h-44）
       卡片圆角 16px（rounded-2xl） 卡内边距 16px（p-4）
       圆形小标 36px（w-9 h-9 rounded-full） 标题 14px/600 单行截断
       描述 12px/2 行  底行 12px：#分类(蓝 #3b82f6) 左、数据右
       角标 12px rounded-md，顶/左各 12px（top-3 left-3）
       搜索框 白底 16px 圆角 高 52px，40×40 绿方钮 绝对定位 right-8px
       hero 渐变 linear-gradient(to bottom right,#16a34a,#22c55e,#f97316)，内容居中
       侧栏选中 #f0fdf4 底 + #16a34a 字；排序条 12px，选中 #22c55e 底
   ★ 断点也照抄参考站：网格 1 列 → 640 起 2 列 → 1100 起 3 列（本站容器比它窄，
     所以 3 列的断点从 1280 提前到 1100，卡片宽度才和参考站一致）
