/* ==========================================================================
   移动端（H5）补丁 —— 实测（375/360/430 三种宽度真实渲染）后按需修正，
   都不改动桌面端表现：
   1) iOS Safari 对字号 <16px 的输入框，聚焦时会自动放大整个页面，
      填单过程中反复缩放极其难受 —— 窄屏下统一提到 16px
   2) 行内按钮原高 26px（.btn-sm），手指点按容易误触，
      尤其订单列表里「标为已收」与「作废」紧挨着 —— 补齐触控高度
   3) #flash 的 top:62px 是按桌面顶栏（约 50px）定的，窄屏下顶栏会换行到
      140px，提示条被压在导航上 —— 窄屏改为底部浮层，彻底避开
   4) 顶栏导航窄屏下换行会吃掉近 1/5 屏高 —— 改为横向滚动，保持单行
