/* 页头 Logo 悬停光晕 —— 七彩霞光带流动。纯 CSS、零图片、零额外请求。
   为什么要拆成父子两层：CSS 规定遮罩在 filter **之后**生效，所以 mask 与 blur
   若写在同一个元素上，模糊出来的光晕会被遮罩重新裁掉。于是
   ::before 负责「按 logo.svg 的轮廓裁出形状」，父层 .logo-halo 负责
   「把已经裁好的形状模糊成辉光」—— 顺序正好。
   .logo-halo 用 inset:0、blur 属 ink overflow：不改布局，也不参与可滚动溢出区，
   不会像 padding/width 那样把横向滚动条带回来。
   blur 取 6px 是算出来的：徽标盒顶距窗口顶 8px（.site-top 上内边距）+ 盒内到
   图形上沿还有 3.4px ≈ 11.4px 净空，而模糊的可见扩散约 2σ。取 6px → 12px 刚好
   收得住；取到 7px 以上，最顶端那圈淡光会被窗口边切出一道硬边。
   注：页脚 logo 是 <div> 不是链接，非交互元素不给 hover 反馈，故不套用 */
