Krysoldev/Ezz-Launcher ? reverse-engineered prompt

Build me a modern Minecraft launcher for Windows that feels clean, fast, and easy to use.

I want it to let people sign in with a Microsoft account or use offline accounts, switch between multiple accounts, and manage multiple game instances in one place. It should support Fabric out of the box, make it easy to handle mods, resource packs, shaders, and game profiles, and include skin management with cached player heads. I also want world import and export, backups, a simple file manager, a log viewer, performance diagnostics, and an auto update system for the launcher itself.

Please make the interface look polished and premium, with a modern layout that feels simple for regular users. It should run on Windows 10 and 11, and use a bundled or system Java setup if needed. If you need to check current docs or best practices while building it, go ahead and look them up online.
