xevrion/breakscale ? reverse-engineered prompt

Build me a browser based system design simulator where I can drag together services on a canvas, connect them, and then turn up traffic to see what breaks.

I want it to feel like a teaching tool for distributed systems, so the app should show real behavior like queues filling, latency getting worse, circuit breakers tripping, retries causing storms, and backlogs building up. Include a handful of ready made example setups, like a simple single server, a load balanced setup, a cache example, async workers, retry storms, rate limiting, circuit breakers, sharding, and autoscaling, so I can load one and play with it right away.

Please make the numbers and charts feel believable and driven by an actual simulation, not just fake animations. It should run entirely in the browser, keep designs local, and make it easy to inspect what each component is doing with plain language explanations. If you need to look up current docs or best practices while building it, go ahead.
