mujairkitten/completionistboard ? reverse-engineered prompt

Build me a simple web app called CompletionistBoard that helps track an uma’s progress toward the Completionist title.

I want a clean page where I can see the main requirements, check things off as they’re completed, and quickly tell what’s still missing. It should feel like a handy personal tracker, not something complicated. Use the icons and visuals if they help make the status easier to read, and make it look nice on desktop and mobile.

Please keep everything in one neat interface with a clear standard view, a calendar or progress style view if that fits, and data that updates smoothly as I mark items complete. If you need to look up anything current online, go ahead and do that. Also make sure it’s easy to edit or extend later, since I may want to adjust the tracked goals.
