tchinso/Favorites — reverse-engineered prompt

Build me a simple static website for NyanKat called Favorites. It should feel like a personal main project page, with a clean home page that introduces the site and links to three areas, App, Game, and Lab.

Keep it easy to browse and friendly, like a small portal for things I like or projects I want to show off. The home page should have a nice header, a short welcome message, clear cards or buttons for each section, and a simple footer. The App section can be for useful tools, the Game section can be for game related experiments, and the Lab section can be for random tests or creative ideas.

Please make it work as a plain HTML site without needing a backend. Use simple styling, make it look good on phones and desktop, and keep the code organized so I can keep adding more favorites later. If anything is unclear, make sensible choices and keep it lightweight.
