   首页（front page）—— inc/home.php 的 4 个短代码
   -------------------------------------------------------------------------
   为什么这几处要写 CSS 而别的交给 Kadence：
     · 核心块（columns / list / buttons）的样式由 Kadence 提供，不必重写；
       一旦重写，父主题升级时两边就会打架。
     · 但「段位卡片的序号」「产品卡的图片比例」「行业计数」是本站特有的语义，
       核心块没有对应概念。只给这些写样式，是刻意的窄口径。
   另外：段位 5 列与产品 6 列在窄屏必须换行。Kadence 的 columns 断点是按
   列数均分的，5/6 列在 1024px 下每列不足 200px，文字会挤成一条。
   所以这两处改用 auto-fit 网格，让列数随可用宽度自己决定。
