/* ============ 9/7 加: 液态玻璃 (Liquid Glass / Glassmorphism) ============
   风格参考: Apple Vision Pro / iOS 26 Liquid Glass
   设计目标:
     - 半透明背景 + backdrop-filter 折射模糊
     - 1px 高光边 (inset linear-gradient 模拟光从上方斜照)
     - 柔和阴影 (投影 + 内部高光, 模拟玻璃厚度)
     - hover 时背景变亮 + 边变亮 + 阴影加深
   兼容性:
     - Firefox / Safari 支持 backdrop-filter
     - 老浏览器 fallback 到 --glass-bg 实色
     - 不影响现有各剧本独立主题 (body.theme-XXX) 因为只改半透明叠加
     - prefers-reduced-motion: 关掉所有 transition/animation
