/* ============================================================
   mobile.css  ——  移动端样式补丁
   说明：
   1. 本文件仅作为 main.css 的补充，不修改 PC 端任何已有规则。
   2. 顶部两条规则在所有宽度下生效，但 PC 上仅把汉堡控件
      隐藏（display:none），对 PC 视觉与功能零影响。
   3. 其余样式全部包裹在 @media (max-width: 768px) 中，仅
      在移动端（及更窄屏幕）生效。
   4. 加载顺序：需在 main.css 之后引入，方可覆盖同名规则。
