     浅黄色…有点乱」：在口播文案页，出稿后才出现的「改一版」卡、以及「出选题」卡，卡头都顶着
     这么一块黄，看着像没渲染完／脏了。
     现在与卡片同色（不写 background 即透明，透出 .card 自己的 --color-bg-card），只靠底部分隔线
     区分卡头与卡体。
     ⚠️ 这是**共享样式**：6 个子页（script / identity / digital-merge-stage / voiceover-stage /
     step1-draft / digital/index）一起变 —— 同款黄每个页面都有，只清一处反而不一致。
     改完记得 bump 这些页面 `<link>` 上的 `?v=`，否则浏览器拿缓存里的旧 CSS。 */
