/* ============================================================
   Help Center（帮助中心）
   设计稿：DTEN Help Center 2.0 Prototype（数值取自原型源码，桌面 / 移动两档）。
   只在帮助中心页面加载（inc/help-center.php），所有规则都在 .hc 作用域里，
   页头页尾是官网的，不受影响。

   主题 legacy 样式的坑（见 style.css / custom/css/style.css）：
   - 标签级 reset 与 h1-h6 / p / button 的默认外观会漏进来 → 下方 :where() 归零；
   - preflight 关闭，border 没有 border-style 兜底 → 同样在 :where() 里补上。
