/* ===== 使用指南（图文版） ===== */
/* 作用域全部挂在 .guide-page 下，不影响其它 info 页。
   颜色/圆角/阴影只用 --joy-* 令牌：三个风格族与夜览只重写令牌，
   因此本页无需（也不许）改动 styles.css。

   ⚠ styles.css 后段有一整套 .info-page .info-content 通用排版
   （h2 / h3 / p / strong / a / ul li / ul li::before，特异性最高 (0,3,1)），
   它们会渗进本页每一颗组件。所以凡与之竞争的规则一律加
   .guide-page.info-page 前缀，靠特异性取胜，不靠「谁后加载谁赢」。 */
