jayjay0713/coolmate-website ? reverse-engineered prompt

Build me a clean modern website for Coolmate using this Next.js app.

I want a polished homepage that feels like a real brand site, with a strong hero section, a few featured sections for products or services, a clear call to action, and a simple footer. Make it look good on mobile and desktop, with smooth spacing, nice typography, and a layout that feels current and professional.

Keep the design simple but premium, and use the existing app structure so I can edit the main page easily later. If you need to check anything about the latest Next.js or styling setup, look up the current docs online and use best practices. Please make the page fully working, responsive, and ready to run locally with the existing dev server.
