   Why Pupulan 手风琴卡（首页 ADVANTAGES，2026-09-20 客户参考图指定）
   stable 态 = 深色圆角卡（仅图标+标题），悬停卡展宽转浅色（白底）露出描述。
   窄态下描述用 opacity 隐藏而非 display:none，宽度动画才平滑；
   .why-body 固定排版宽度，展宽过程中文字不回流，由卡片裁切逐渐露出。
   注意：本组选择器特意带 .why-acc 前缀且放在 .reveal.is-in 之后——
   同特异性下后来者赢，卡片自身的 flex-grow 动画才不会被入场动画的
   transition 声明覆盖。≤1080px 在下方 Responsive 区退化回网格布局。
