Usama-7800/nuxt-ui ? reverse-engineered prompt

Build me a clean modern Next.js homepage for a small UI showcase site.

I want it to feel polished and responsive, with a nice hero section, a few feature cards, a simple navigation bar, and a footer. Use the existing project setup and make it look good on mobile and desktop. Keep the design minimal, bright, and easy to read, with good spacing and smooth hover states.

Please wire it up so the main page actually looks finished instead of just the default starter screen. If there are any current docs or best practices that would help, feel free to look them up online first. Make sure the code is tidy and easy to edit later, since I may want to add more sections after this.
