/* ==========================================================================
   硅基办公 · 日夜模式（v0.1.80）
   ---------------------------------------------------------------------------
   夜 = 原来的样子，一个字都没改（默认就是这个）。
   日 = 把两个「颜色族」翻过来：
        · --wb-ink-rgb     全项目那些 rgba(255,255,255, X) 的墨色
                           （毛玻璃底、描边、次级文字全走它）
        · --wb-sheet-rgb   菜单 / 浮层那种实心面板的底色
   两个三元组一换，外壳（桌面 / 任务栏 / 开始菜单 / 窗口 / 驾驶舱）和所有 App 的
   毛玻璃组件会**一起**翻过去 —— 因为 v0.1.80 已经把全项目的写死色收进这两个
   token 里了，没有第二套配色。剩下少数几处「本来就该是深色」的地方
   （桌面背景、壁纸、驾驶舱的星空格栅）在这个文件里单独给一套日间值。

   想加第三套主题（比如「暖色」「高对比」）：照 day 这一段再写一份
   html[data-theme="xxx"]，然后在 desktop.js 的 THEME_LIST 里加一条。
