snigglaberry/crit-launcher ? reverse-engineered prompt

Build me a simple open source Minecraft launcher called Crit Launcher, using Python with an HTML based interface.

I want a clean desktop app that can open like a real launcher, let me set up and launch Minecraft, and look polished with a custom themed UI. It should feel modern, support Discord presence if that’s part of the project, and be easy to package into a single Windows app. Include the usual launcher basics like a main screen, account or login flow if needed, and buttons or controls for launching and settings.

Please make it work as a standalone project I can run and then package for release, and keep the code easy to follow. If you need current docs or best practices for anything, look them up online first.
