bprateeek/systems-lab — reverse-engineered prompt

Build me a single page web app called Systems Lab that helps people learn system design without needing a backend.

It should open by just double clicking index.html in a browser, work mostly offline, and feel polished enough to use as a study tool. I want 13 system design topics, covering basics like storage, transactions, replication, partitioning, consensus with Raft, caching, batch jobs, streams, search, networking, and reliability.

For each topic, include short notes, a simple “how to use this lab” explanation, an interactive mini lab people can play with, and an interview style answer they can quickly review. Include useful labs like a partitioning playground, cache eviction simulator, live Raft cluster demo, and resilience playground with rate limiting and circuit breaking.

Also add search, deep links with URL hashes, and a Study Sheet mode that shows all notes together so someone can print it or save it as a PDF. Keep it all in one clean HTML file with nice styling.
