     ① 页头卫星轨迹 —— 内页第一屏 ::after，商品页由 :has(.split)
        精确排除（标题与价格会被压）。
   ⚠️ 前者用「一张预制无缝贴片」，切勿改成多层瓦片式 radial-gradient

/* ===========================================================
   候选 A —— 页面级星空（延伸既有的星点语言，不发明新花纹）
   ---------------------------------------------------------------
   做法：直接给 body 的本底背景挂「一张无缝星空贴片 + 一层稀疏点缀」。
   ★ 内容面（.card / FAQ 区 / 页脚）本来就不透明，
     星点只在真正空着的黑区出现 —— 文字与商品图底下零干扰。

   ⛔⛔ 血泪教训：**不要用 `body::before{z-index:-1}`**。
   本站 `body{background:var(--ink)}` 自带不透明底色，
   负 z-index 的伪元素会被**父元素自己的背景**整个盖住 —— 视觉上
   与"没加"逐像素完全相同（实测差值 = 0，还骗过了肉眼看缩略图）。
   要么挂在 body 的 background-image 上（本方案），
   要么把 z-index 提到 0 并给所有内容面加 z-index（侵入大、易漏）。
   ⚠️ 另一个反面教材：别用"3 层瓦片式 radial-gradient"叠出星空，
      实测会让软件光栅化卡死；用一张预制贴片，层数压到 1~2 层。

   候选 D2 —— 卫星轨迹 + 地平线光晕（"进画"版：放进页头夜空）
   ---------------------------------------------------------------
   和 D1 的区别：D1 把图案挂在全屏固定层上（会被卡片遮挡、随滚动滑动）；
   D2 直接画进「内页第一屏」那只夜空容器（main>section:first-child
   的 ::after 层），成为那片天空的一部分 —— 天空本来就在这里，
   卫星当然该在这里划过。

   做法：整段覆写该 ::after 的 background 列表，把原有的
   （暗角 + 山体压暗 + 细颗粒）三层完整保留，只在最前面加两层：
     ① 卫星轨迹弧线
     ② 卫星头部光晕（独立 radial，避免被非等比拉伸成椭圆）
   ⚠️ 覆写 ::after 必须原样保留原有三层，漏掉会出现"山体不再压暗、
      底部不接 --ink"的接缝，页头与正文之间会露一条硬边。
