   qing-hero  —  首屏 Hero（背景图 + 眉标/标题/描述/按钮组）
   前缀: qh-
   结构与「关于页首屏 Banner」(.qah-*) 完全一致，只多一个按钮组。

   宽度模型（三层，各管一件事）：
     .qh-wrap   高度 + 定位 + flex 垂直居中。不声明宽度。
     .qh-scene  absolute 背景图 + 渐变遮罩。
     .qh-inner  max-width + margin:0 auto + padding + border-box。

   通栏由外层 Elementor 容器负责（把容器「内容宽度」设为全宽），
   小部件本身不做任何突破容器的操作。
