   ★ 两条纪律（这个项目踩过的坑）
   ----------------------------
   1. **全部限定在 `.pc-page` / `.pca-page` 内**，不写裸选择器 ——
      否则会污染主系统其它页面（主站有大量 .btn / .card 之类的通用类名）。
   2. **优先用字面色值，慎用「惰性引用」的 CSS 变量**。
      踩过的坑：`.gzh-scope` 上定义
          --g-primary-light: var(--primary-light, #dbeafe);
      Chromium 在**伪元素**（如 ::file-selector-button）上解析会拿到空串，
      导致整条声明失效（表现为「按钮样式没了」）。
      所以本文件不用 var()，全部写字面色值。
   3. `.pc-note` / `.pc-card` 若用 <button> 必须清掉默认样式。
