/* ==========================================================================
   兼容层：购物车被「客户端中心」布局包裹时（/cart 实际位于 .sky-content 内）
   --------------------------------------------------------------------------
   根因：.shopping-cart-page 原为 position:fixed;left:0;right:0;z-index:auto
         （视口全宽，不受 .sky-main-content{margin-left:--nav-l-w} 约束）；
         而客户端中心有固定全局侧栏 .sky-sidebar
         （position:fixed;width:--nav-l-w:200px;不透明;z-index:99）
         与固定面包屑 .sky-container-fluid（z-index:88）。
         视口 < 约 1820px 时，购物车左列会被全局侧栏从左侧盖住约 190px ——
         表现为分类标题变空白方块、子项只剩最末一个字、搜索框只剩尾部。
   修复：桌面端在 .sky-content 作用域内【直接隐藏全局侧栏 .sky-sidebar】
         （display:none，彻底移除覆盖源，不再依赖 z-index 层叠博弈），
         并释放主内容区/面包屑为全宽；购物车主体改为沉浸式全宽、
         顶部对齐客户端中心顶栏下方，保留购物车自带的分类栏与「返回」栏。
   说明：仅桌面端生效；≤992px 已由上方媒体查询切换为文档流布局，无需处理。
