PurelyAnecdotal/gradecompass ? reverse-engineered prompt

Build me a polished grade calculator web app called GradeCompass that helps students figure out where they stand in a class.

I want it to let people enter assignments, weights, scores, and extra credit, then instantly see their current grade and what they need on future work to reach a target grade. Make it easy to add, edit, and remove categories and assignments, and keep the interface simple and friendly on desktop and mobile.

Please make it feel like a real product, with clear results, helpful labels, and a clean modern design. Include a branded homepage, a calculator view, and sensible empty states so it still feels good before anything is entered. If you need to look up current docs online for SvelteKit or anything related, feel free to do that.

Also, set it up so the app can be hosted easily, and make sure the branding text, icon, contact email, and repository link are easy to change later.
