Build me a clean Next.js website in TypeScript that looks polished out of the box and is easy to edit. I want a simple starter app with a nice homepage, responsive layout, and a good default visual style using modern fonts and spacing. It should be set up so I can open the main page and quickly replace the content with my own ideas, without having to fight the code.

Please make the app feel production ready, with reusable components, a tidy structure, and sensible defaults for styling. Keep it lightweight and fast, and make sure it works well on mobile and desktop. If you need to check current Next.js docs or best practices, go ahead and look them up online.

I mainly want a solid foundation that I can build on, so set up the project in a way that makes future pages, sections, and components easy to add.
