   世界技能大赛 · 网站技术 —— 站点样式
   ------------------------------------------------------------------
   设计语言沿用同目录项目（webPPT/index.modern.html）：
   · 琥珀 / 橙 主题色 + 深棕底
   · 方格背景 + 随机方格边缘呼吸发光 + 细颗粒噪点 + 四周压暗
   · 玻璃拟态卡片（--glass + backdrop-filter）
   · 渐变文字、胶囊 chip、圆点导航、进度条
   · 3D 倾斜 + 跟随高光、分层错峰入场动效
   与演示稿的差别：本站是滚动式长页，因此背景改为 fixed 且格子随滚动淡入淡出。
