iampremjena/Terrathon ? reverse-engineered prompt

Build me a polished Next.js site for Terrathon that feels like a real modern product landing page. I want a clean homepage with a strong hero section, a few simple content sections, and a nice responsive layout that looks good on both mobile and desktop. Keep the design minimal but professional, use reusable components where it makes sense, and make the page easy to update later.

Please set it up so the main content lives in the normal app page, with supporting components, hooks, and utility files organized cleanly. Use sensible defaults for styling and typography, and make sure the whole thing runs smoothly with the standard dev server. If you need anything current from the Next.js docs to make it best practice, look it up online.
