      repeat(auto-fit,minmax(260px,1fr)) 与 .capabilities-grid 的 3 列基础规则，
      把 ≤640 的媒体查询（单列）盖掉了（优先级 0,2,0 > 0,1,0）→ 3×175+间距=563。
   2) 法务页表格 114px 溢出：表格 min-content 宽度大于手机宽度。
   3) 15 个表单输入框 font-size:14px → iOS 聚焦自动放大页面。
   4) 30-46 个可点元素高度 <40px（品牌 logo 30、导航 35、页脚链接…）。
   5) iPhone 刘海/底部横条：需要 viewport-fit=cover + safe-area 内边距。
