/* ----------------------------------------------------------------
   自适应网格写法说明（本文件所有多列网格统一用这一套）
   ----------------------------------------------------------------
   旧写法：repeat(3, 1fr) —— 永远 3 列。1440 屏每列 384px，
           1024 屏每列 300px，中间没有过渡，窄到断点才一刀切成 2 列。

   新写法：
     repeat(auto-fit, minmax(max(最小列宽, calc((100% - 间距总和) / (列数 + 0.4))), 1fr))

   - 容器够宽时，(100% - 间距) / (列数+0.4) 一定大于 1/(列数+0.4)，
     所以只放得下「列数」列，不会多出一列；
   - 容器变窄，这个值跟着变小，列宽跟着变小；
   - 窄到每列不足「最小列宽」时，自动少一列。
   结果：列数随屏幕宽度连续变化，两个断点之间不再有死区。
   下面每个网格的 0.4 是余量系数，保证算出来的列宽刚好能放下目标列数。
