/* ============================================================
   素脸云 设计系统 CSS  ·  v2 (Apple 浅色 · 隐私强调 · 简约主色)
   ------------------------------------------------------------
   设计取向：
   - 浅色为主，系统字体 + 光学字距（Optical Sizing / Tracking）
   - 半透明毛玻璃材质（backdrop-filter）承载导航与工具栏，内容在其下滚动
   - 分层柔和阴影 + 加大圆角，营造 Apple 式空间层次
   - 即时按压反馈（:active 缩放）+ 卡片 materialize（悬浮时浮现而非单纯变色）
   - 隐私强调：克制靛蓝主色 + 毛玻璃/锁盾视觉语言，强调「端侧 · 本地销毁」
   仅改视觉层（CSS），不触碰任何 JS 交互逻辑。
