/* ============================================================
   恒力达 · 公共头部 / 底部样式 common2026.css
   ------------------------------------------------------------
   特点：不含任何全局元素选择器（body / a / img / ul / li / h* 等），
        所有复位都限定在 .topbar / .site-header / .site-footer / .rail
        内部，因此可以和旧模板的 qz.base.css、style.css 同时引入，
        不会改变内页原有内容的排版。
   用法：所有页面在 </head> 前引入；首页再额外引入 home2026.css。
   维护：本文件是 home2026.css 中「头部 + 底部」部分的公共子集，
        修改导航或页脚样式时请同步两个文件。
