Cross-Platform Bridge Latency Simulator

Every cross-platform mobile framework has to move UI updates from its logic thread to the native rendering thread, and how it does that determines whether your app feels smooth or janky. This simulator models that hand-off as a real single-server queue: UI-update messages arrive at a chosen rate, a bridge architecture serializes each one before it can be rendered (React Native's classic bridge, Ionic's WebView), while a direct-call architecture (Flutter's compiled renderer, JSI) skips serialization almost entirely. Watch packets queue up at the bridge gate as load rises, and see the live frame-rate, average latency and jank-percentage readouts track the underlying M/D/1 queueing math in real time.
