This weekend, I set out to get some high-resolution screenshots of zebra-algo (you may remember it as the now-defunct CodeMarshal or algo.codemarshal.org). My motivation was to document its design and features, as zebra-algo is a competitive programming contest platform I built back in 2014. The plan was straightforward: run it locally, open it in a browser, take the screenshots, and be done. Simple, except the codebase is twelve years old, making things tricky.
