   一段时间，再走 .4s 淡出 —— 就是「一闪而过」。

   修复：<head> 里的内联脚本在 body 渲染前读 localStorage，若判定不该弹，
   就给 <html> 加 .intro-off，让 intro 从第一帧起就 display:none。

   必须用 display:none 而不是 opacity:0 —— 后者会触发上面那条
   transition，照样闪一下。此规则也不能写进 .intro.gone，因为正常关闭

/* =========================================================================
   iOS Safari 图标按钮居中兜底
   -------------------------------------------------------------------------
   起因：移动端列表卡片上的「+」在 iOS Safari 里偏向右下，PC 正常。
   Chromium（含移动视口模拟）复现不出来，DOM 几何是精确居中的，
   所以问题出在引擎差异，不在布局数值上。

   三个叠加的成因：
   1. 只写了 appearance:none，没写 -webkit-appearance:none。
      iOS Safari 15.4 之前只认带前缀的属性，不写则保留原生按钮外观，
      连带平台自己的非对称内边距。
   2. 没有显式 padding:0，于是吃 UA 默认值。实测 Chromium 给 1px 6px，
      WebKit 给的是另一套，图标因此在不同引擎落在不同位置。
   3. 在 <button> 上用 display:grid + place-items:center。WebKit 长期
      对表单控件的 flex/grid 支持不完整，会把内容包进匿名盒并忽略这些
      属性；一旦忽略，svg 退回行内流坐在文字基线上——视觉上正是"偏下"，
      再叠加第 2 条的非对称 padding 就成了"偏右下"。

   已用最小复现页验证：模拟 grid 失效时确实产生 3px 偏移；
   本方案在 grid 与 flex 同时失效的最坏情况下仍然居中。

   注意这里只补齐防御性属性，不改任何尺寸、颜色或圆角，
   所以对现有视觉没有影响。
