/* ══════════════════════════════════════════════════════════
   专栏卡片 —— ColumnSeries 短代码 [column slug="x"] 的渲染结果
   （mode="compact" 为紧凑卡）

   为什么放 post.css 而不是 base.css：
   卡片只出现在 .article-content 里，而 post.css 恰好在 $this->is('single')
   时加载、且排在 base.css 之后 —— 这样 .column-embed 系列规则天然压过
   .article-content p 之类的正文规则，不必动 !important。

   封面为什么是背景图而不是 <img>：
   卡片位于 .article-content 内，任何 <img> 都会被主题的灯箱
   （main.v2.js 收集 .article-content img）与图片评论徽标接管，
   于是专栏封面会混进正文图集、还被挂上评论按钮。背景图避开整条链路。

   颜色全部走主题变量，深色模式自动跟随，无需另写 html.dark 分支。
