/* ==================== 内页 Header 遮挡修复 ====================
   父主题 (vw-courier-serivce-pro) 已知 Bug：

   修复方式：精准限定 body class，仅给内页内容区域加 padding-top，
   首页和其他正常页面完全不受影响。

   WordPress body class 对照表（请勿凭记忆猜测）：
     archive 页  →  body.post-type-archive-ax_product
     category 页 →  body.tax-ax_product_cat
     tag 页      →  body.tax-ax_product_tag
     detail 页   →  body.single-ax_product

   对应的容器 class（请查阅模板文件确认，不要猜）：
     archive-products.php 中用 .page-header-bar + .list-layout
     single-products.php 中用 .product-detail-section + .breadcrumb-nav
