   主张网 · 液态玻璃风（Liquid Glass）
   说明：Apple Liquid Glass 官方规范仅用于苹果平台（iOS 26 等），
   官方未提供任何网页 CSS 实现。本文件是"网页近似
   （approximation）"：backdrop-filter 折射模糊 + 分层内描边 +
   镜面内高光 + 胶囊形态 + 流动彩色光斑。
   与"玻璃拟态风"的差异：更透的填充（.42）、更强的镜面内高光、
   边缘折射描边（三层 inset）、胶囊/水滴形态（导航与按钮 999px）、
   海蓝 #0A84FF 强调、天蓝→白→淡青流动底。
   仅由 CSS/JS 实现整站视觉，HTML 与主目录保持零差异。
