/* ============================================================
   v23 兼容性修复（Safari / 夸克 / 移动端 WebView）
   生成日期: 2026-10-26
   ------------------------------------------------------------
   问题 1：.m-bar 移动端底部导航永不显示
     原因：`.m-bar{display:none}` 位于 @media 之外且写在
           @media 之后，层叠优先级相同 → 覆盖了媒体查询内的
           `.m-bar{display:flex}`。所有浏览器都命中，非个别内核。
     修复：把隐藏态放进 `@media(min-width:981px)`，窄屏恢复 flex。

   问题 2：position:sticky 缺少 -webkit- 前缀
     原因：旧版 Safari / iOS WebView / 夸克旧内核需要
           `-webkit-sticky`。缺失时 .mainnav 退化成 relative，
           滚动时导航不再吸顶（表现为"布局错乱"）。
     修复：补前缀 + 补 top 值。

   问题 3：flex + gap 老内核无间距
     老版本 Safari(<14.1) 与部分安卓 WebView 不支持 flex 的 gap，
     会导致导航项、按钮组挤在一起。
     修复：对关键横向 flex 容器用 margin 兜底（不破坏新内核）。

   问题 4：iOS Safari 点击延迟 / 字体自动放大
     修复：-webkit-tap-highlight-color 透明；对输入控件设 16px
           防止聚焦时页面被强制缩放。
