   规格照抄参考录屏里的 stacked-cards：每张卡钉在视口顶部附近不动，
   后一张从前下方滚上来把前一张整块盖住 —— 没有缩放、没有淡出、纯覆盖。
   录屏视口 1210×588 实测：钉住 top 26px / 卡高 399px(67.9vh) / 卡宽 1079px(89.2vw)
   / 卡间距 13px / 圆角 ~12px / 卡面 #161617 压在 #090909 底上
   / 内边距 24px / 图文列宽 579:403(≈1.45:1) 列间距 50px / 标题 ~30px。
   两处不得不适配的偏差：① 本站导航是 56px 固定条，钉住位下移到 74px，
   否则卡片顶边会被吸顶毛玻璃糊住；② 卡面必须保持不透明，
   半透明会让被盖住的那张透上来，堆叠层次直接失效。
   ③ 卡高 2026-09-29 按用户要求从 68vh 压扁到 48vh（他圈了红框：604px → 433px，即 71.7%）。
   录屏原比例是 67.9vh，压扁后卡片四周露出的背景更多、图被 cover 裁得更紧。
