   后台电脑端布局（2026-09-25 第三次调整，用户两次反馈「留很多白的地方 / 模块太大」）
   手机端一直是正常的，所以这一整段只作用于 ≥1024px。

   原来电脑端是「一行 1180px 全宽堆叠 + 顶部两列网格」，两个毛病：
     1) 顶部三张卡（添加网站 / 网站背景 / 站点头像）走的是 grid，
        卡片高矮不齐 —— 「添加网站」下面空一大片，「站点头像」右边也空一片；
     2) 其余卡片拉满 1180px 宽，又宽又空，整体显得臃肿。

   这里用「多列瀑布流」治：column-count 会自动把卡片平摊到两列，高度不齐也不会留洞；
   「分类与网站管理」用 column-span: all 保持整行通栏。
   基础上再把字号、内边距、列表行高整体压一档。

   后台电脑端收口（2026-10-06）

   这里把电脑端改成明确的 CSS Grid：普通卡片两列，文案卡和列表卡整行，
