流体交互层:按压反馈 + 真半透明材质 + 主题交叉过渡 + 弹层材质化

按 apple-design(Designing Fluid Interfaces)审查落地:
- 全站补 :active 按压缩放反馈(按钮/tab/链接/命令面板/前后栏导航),交互元素加 touch-action
- TopBar、首页标题栏、浮动主题钮改 color-mix 半透明 + blur 真材质,配 reduced-transparency 回退
- 主题切换 250ms 交叉过渡(theme-anim 瞬时类),消除亮度突变
- CommandPalette/ShortcutsPanel 过 <Transition name="pop">:scrim 淡入 + 面板自顶部锚点 scale 进入,退出原路返回
- 首页标题栏收缩由二值跳变改为滚动进度 --sq 连续插值(16–56px)
- reduced-motion 例外:弹层保留短交叉淡入,禁位移与主题过渡
- 触控目标增大(主题钮 40/44px、tab、后台导航项),文章大标题负字距 + 收紧行高
