Distributed System in a Single Tab

 Build an interactive distributed-system simulator that runs entirely inside a browser tab. Represent services, queues, databases, caches, workers, clients, network links, failures, retries, timeouts, and load as live visual objects. Allow users to inject latency, packet loss, service crashes, duplicate messages, stale caches, and traffic spikes while watching the system respond in real time. Include controls for changing architecture and compare how different designs behave under identical failure scenarios.
