/* ============================================================
   redesign.css · MetaMe Azure AI Foundry 风全站统一 UI
   ------------------------------------------------------------
   参考 https://azure.microsoft.com/zh-cn/products/ai-foundry
   核心视觉：深蓝紫渐变 hero + 白字居中 + 浅灰内容底 + 白卡片分区 +
   圆角胶囊 tab/按钮 + Fluent 阴影。除 3D 首页与直播间外全部页面生效。
   3D 首页（home.css : body:has(.hero3d) …）与直播间（live.css : .live3d*）
   用 body:not(:has(.hero3d)):not(:has(.live3d)) 双重守卫隔离，零泄漏。
   颜色全部走 tokens.css --tech-* 语义层，本表不硬编码新色值。
