/* ============================================================

   设计约束：≤760px 为手机/小平板，≤480px 进一步收紧。
   三条必须守住的底线（首版全都踩了）：
     1) 表格不能靠 min-content 撑开布局视口 —— 窄屏把 table 变成
        横向滚动容器（display:block + overflow-x:auto），整站才不会
        被一张宽表带偏。
     2) flex 子项默认 min-width:auto，长文本/下拉框不肯收缩就会溢出。
        凡是 flex 里放 input/select/长文本的，一律 min-width:0。
     3) 顶栏与后台导航必须允许换行，否则窄屏直接横向溢出。
