/* ==================== 电脑版专属：顶部搜索框下拉面板（#desktopSearchPanel） ====================
 * 只在 min-width:769px 生效；手机版（≤768px）面板永远 display:none，JS 侧也会先判断断点，
 * 手机端搜索行为/布局完全不受影响。面板以 .navbar-search 为锚点 absolute 展开，
 * 不占文档流、不推动页面、不改变 Header 高度。层级位于 .site-top-fixed（z-index:100）内部，
 * 天然高于 Hero/卡片/分类导航，同时低于 Auth Modal（z-index:2000+）。
 * ==================== */
