/* ★ 卡片默认【占满一行】，想变窄的自己声明。
   
   .grid 是 12 栅格，而 CSS 里没写 grid-column 的卡片会被自动放进
   【一格】—— 也就是屏幕的十二分之一。表现出来就是几张卡并排缩成
   几根竖条，里面的字一个字一行（老板截图里学习库那四条就是这样）。
   
   这个坑之所以反复踩，是因为它是"忘了写"才触发的：加一张新卡、
   忘了补一条 grid-column，页面就塌一块，而且不报错。
   所以把默认反过来 —— 忘了写就是整行，最多是宽了点，不会塌。
   
   用 :where() 是为了让这条规则【零特异度】：下面 .summary（span 4）、
   .plan-health 这些真正想变窄的，照旧生效，一个字都不用改。 */
