   ★ 移动端排版层  (max-width: 768px)
   ------------------------------------------------------------
   手机端不是桌面版纵向压扁的结果，而是另一套排版：
     · 列表改横向卡片（左图右文），单卡高度 470px → 约 130px
     · 版块间距、内页 banner、页脚整体收紧
     · 页脚由 4 段纵向堆叠压成 2×2 栅格
   本层刻意放在文件最末：既要盖过前面所有桌面规则，也要盖过
   foot.html 中在本文件之后加载的 Swiper / AOS 样式。
   文件前部残留的旧移动端规则会被本层逐条覆盖，无需删除。
