/* ===== 顶部导航吸顶：与主题「首页顶部菜单透明」机制协同 =====
   当 body.header-transparent 时，主题自带规则：
     .header-transparent .site-header:not(.navbar-sticky) { background:transparent; color:#fff; ... }
   所以：
     - 未滚动 / 未越过阈值：header 无 class，主题保持透明
     - 滚动越过阈值：JS 给 .site-header 加上 .navbar-sticky → 自动恢复背景+颜色+阴影
   下面我们只补吸顶的定位（position/width/z-index）和过渡，不覆盖主题原有颜色。
