     首页小修（2026-08-31 15:06 · patch4）· 5 个区块头统一重排为 Hero 版式
     范围：#page-home 下 5 个区块（WHY NOW / CAPABILITIES / SERVICE PLANS / INDUSTRIES / HOW WE WORK）
     手法：HTML 把 sec-head 加 sec-head-new 类（业务逻辑零改动）+ 纯追加覆盖
     视觉对齐 Hero 区（小字 pill 蓝点 + 衬线大号中文标题 + 描述，左对齐，纵向堆叠）
     关键修补：#page-service 历史未定义 --xz-serif/--xz-mono，导致 .sec-marker 用 var() 回退默认无衬线；本批统一补齐
     ========================================================== */
  /* 行知字体变量只定义在 Hero 区块头作用域内（patch7 修正）：
     不能放 #page-service 上——否则 service 页内容区（.pack h3/.advisor h3/.adv-plan h4/.ind h3 等）
     的 var(--xz-serif)/var(--xz-mono) 也会跟着生效，把原本无衬线的内容区标题全部变成衬线/等宽体。
     patch4 就是因此误伤了内容区，本 patch 把变量收窄到 .sec-head-new 内，区块头 Hero 样式不受影响 */
