/*==========================================================================
  经典案例 · 卡片（2026-09-23）
  版式参考：客户提供的 "Choose Your Destination" 卡片模板（默认态 + hover 态）
  设计要点：
    · 竖版满图卡片（2:3），图片铺满整卡、圆角裁切
    · 底部深色渐变压边，承载「图标 + 标题 + 副标题」
    · hover：卡片上浮、图片缓慢放大 → 标题微上移、胶囊按钮向下展开
  作用域：全部使用 .cc-* 前缀，不影响站内其它页面沿用的 .case-card
