   WINTEL — page styles
   ------------------------------------------------------------
   与 site.css 配套：site.css 放全站共享样式（基础 + 页头页脚 + 共享组件），
   本文件放各页面的具体版式。

   约束（重要）：本文件是全站生效的，因此
     1) 不写裸元素选择器（h2 / ul / li / p ...），一律挂在类下面；
     2) 需要作用于"无类名列表"时用 .card > ul:not([class]) 这种精确写法，
        避免顺带把 .tick / .dash / .chips / .cares 之类的列表样式改掉。
