/* 信息技术卡：整卡可点 + 标签行里的「SCA 实战」可独立跳转。
   做法：整卡不是 <a>（否则无法在标签行内再放 <a>，嵌套 <a> 属非法 HTML，
   浏览器会拆开嵌套导致整卡点击失效）。改用一个铺满的 <a> 做点击热区。

   层叠安排（关键，容易踩坑）：
     z-index:0  → .s-seal / .s-arrow，压在热区之下
     z-index:1  → .s-cardlink 热区，接住整卡点击
     z-index:2  → a.s-sub（标签行里的 SCA 入口），抬到热区之上才能独立点
   ⚠️ .s-body 只能用 position:relative、**不能设 z-index**：
     一旦写了 z-index（哪怕 0）它就会创建层叠上下文，
     里面的 a.s-sub 的 z-index:2 就被困在 .s-body 内，永远压不过热区。
     保持 z-index:auto 才能让 s-sub 参与外层层叠、超过热区。 */
