/* ============================================================
   小涵互联 · 手机端收口层（mobile3.css）
   ------------------------------------------------------------
   定位：mobile.css → mobile2.css 之后最后加载，只做「补缺口 + 收口」，
        不重复 mobile2 已完成的模块重排，避免互相打架。
   解决：
   1) 全站缺全局 box-sizing → width:100% + padding 的元素横向溢出
   2) 触控目标 < 44px（页脚链接、更多、社区行内操作、广告位）
   3) mobile2 未覆盖页面的标题/留白（pay、apps、about、agreement、错误页）
   4) 登录/注册/找回 输入框字号 < 16px（iOS 聚焦自动放大）
   5) 表格横向溢出、图片变形、破图空框
   6) TabBar 安全区与点击反馈、横向滚动标签条的可发现性
   桌面端（>820px）零影响
