   反向入侵 · 触发瞬间「夺屏」特效（2026-08 新增）
   --------------------------------------------------------------
   触发反向入侵的一刻不再让 User 看到"从 Char 手机桌面平平无奇地退回
   查手机主界面"，而是：整屏抖动 → 雪花噪点铺满 → 模型以 Char 阴暗面
   口吻现写的重影文字浮现（颜色 / 重影是否扩大 / 是否裂屏由模型决定）。
   兼容性要点：
   - 雪花优先用 <canvas> 低分辨率噪点（所有主流内核支持）；canvas 不可用
     时回落到 CSS 渐变噪点动画（.reverse-invasion-glitch-noise-fallback）。
   - 重影用 ::before/::after + attr(data-text) 双拷贝（全内核支持），
     不依赖 @property / backdrop-filter 等新特性。
   - 抖屏只作用在特效层自身（stage），绝不 transform body/html——
     避免 iOS Safari / 各安卓 WebView 上 position:fixed 元素错位的老坑。
   - prefers-reduced-motion: reduce 时自动关掉抖动与高频闪烁。
