/* 分站「全部分类」修复（0919b）：分类面板 + 手机端分类条
 * 兼容性：不用 inset / min() 这类新写法——老 iOS(≤14.4)、旧安卓 WebView、X5/UC 内核不认，
 * 面板会变成 0×0 看不见，而页面滚动已被锁住 = 整页卡死。 */

    /* 旧的分类条保持「单行横滑」。只修两点：
       ① 加载完成前 200px 的占位高度；
       ② 首页内联样式给每个分类写了 width:100%（原本给三列网格用的），横条里就变成「一格占满一屏、只露一个」。
       不能改成自动换行：每格 100% 宽时会变成一行一个的竖排长列表，把商品区顶到一屏半以外。 */
