/* ============ 白色工作台：小程序 / 站长管理 / TS3 点歌台 / 作品集 ============
   ⚠️ 关键：整套变量重定义必须用 html[data-theme="light"] 做祖先门控。
   原因：html[data-theme="dark"] 与 body.light-workspace 优先级同为 (0,1,1)，
   而本块在文件末尾 → 后者胜出 → 用户在深色主题下访问这 4 个页面时，
   html 明明挂着 data-theme="dark"（--bg:#121212），body 却被强制覆写成
   --bg:#f7f8f8，页面永远白底。这就是"不同页面自动变回另一种主题"的根因。

   门控后行为：

     · 深色主题 → 本块不生效，工作台跟随全局深色变量

/* ============================================================
   丝滑页面切换 —— 跨文档 View Transition（渐进增强，零依赖）

   原理：站点是 SSR + 普通 <a href> 整页导航，浏览器原生跨文档 VT 最贴合。
        @view-transition { navigation: auto } 让浏览器自动接管整页导航：
        旧页冻结成快照淡出、新页淡入，两层交叠 → 不会出现白屏。

   渐进增强（三层，互不叠加）：
     1) 支持跨文档 VT  → @view-transition 生效，禁用「入场动画」
        （靠 @supports (view-transition-name:none) 门控，避免双重动画）
     2) 不支持跨文档 VT → 走下面的 dw-page-in 入场动画（Safari/Firefox 也平滑）
     3) prefers-reduced-motion: reduce → 全局兜底(见上方 885 行)把时长压到 .01ms

   性能约束：只动 opacity / transform（合成层），绝不碰 width/height/top/left/margin
