Kishan-shah12/cubosapiens_world-tools ? reverse-engineered prompt

Build me a browser first website called CuboSapiens that feels like one place for free tools, small games, and simple AI utilities.

I want it to be easy to browse on desktop and mobile, with a clean homepage that makes it obvious there is no signup and no paywall. It should organize things into tool and game sections, and let new apps be added in a modular way so the site can grow over time. Include a few example pages like a QR generator, a markdown editor, a snake game, and a quiz game, even if they are just simple starter versions for now.

Make the design modern, fast, and open source friendly, with a clear search or browse experience and a polished landing page that explains what the platform is. If anything needs current docs or best practices, look them up online and keep the setup simple so I can run it locally right away.
