 - 中：Emby 播放回报必须沿用 PlaybackInfo 返回的 `PlaySessionId`/`MediaSourceId`，并将开始、进度、停止事件串行化；把回报协程绑定到播放器 Composable 生命周期会在返回页面时丢失停止事件。
 - 高：液态玻璃不能以“API 版本高”作为唯一启用条件；Kyant Backdrop 还需通过设备安全门和运行帧率门控，低帧率/不安全 GPU 必须在创建 LayerBackdrop 前降级，避免 RenderThread 崩溃。
 - 高：玻璃模式已改为用户手动选择，不能再用 Choreographer 帧率变化自动切换；但模拟器/低版本仍必须在创建 Kyant LayerBackdrop 前保留硬件安全门，避免 RenderThread SIGSEGV。
