   卡片分三列，每一列是一个 .col 容器（结构由 build.py 的 COLUMNS 决定）。
   窄屏三列竖着叠成一列；>=1024px 才并成三列。

   为什么不用 CSS 的 `columns` 瀑布流：它按文档顺序依次灌满一列再灌下一列，
   优化目标是「让最高的那列尽量矮」，不是「三列一样高」。skills 单张 683px，
   第三列每次只到一半就结束，实测三列底边差 265px，右下角一大片空 —— 
   这就是「排版不对称」的来源。
   为什么也不用 grid-row 给卡片逐张定位：grid-row 指的是网格的第几行，
   同一行索引的卡片会被强制对齐到同一个 y，矮卡片下面要空着等高卡片，
   比瀑布流更糟。列容器各堆各的才对。 */
