/* ============================================================
   DigMeta · 超脑训练  官网样式 V2（2026 视觉升级版）
   品牌色与 App 一致：#2C79F4 蓝 + 鲸鱼 logo
   ------------------------------------------------------------
   设计原则：
   1. 色彩分层 —— 主蓝 + 靛/紫/青/琥珀 辅助色，打破单一蓝
   2. 质感分层 —— 玻璃拟态 / 多层阴影 / 渐变描边 / 光斑装饰
   3. 节奏分层 —— 浅底 / 白底 / 深底 交替，区块间有过渡
   4. 动效克制 —— 进场淡入上移、悬停微浮、数字滚动
