/* ============================================================
   全站共享主题令牌 theme.css（2026-08-22 由各页内联 :root 提取统一）
   三态主题：
   - 默认深色 :root
   - 浅色  html[data-theme="light"]（site.js 切换）
   - 系统  @media (prefers-color-scheme: light) html:not([data-theme="dark"])
   依赖：site.js 驱动；site.css 与各页内联样式消费这些变量。
   加载顺序：位于各页内联 <style> 之前（变量定义先于消费）。
