Build me a simple modern React website from this starter.

I want a clean single page app that looks polished and works well on desktop and mobile. Use the existing setup, keep it lightweight, and make the page feel finished with a nice layout, smooth sections, and responsive styling. Please use the tools already in the project for styling so it feels consistent and easy to maintain.

Make the home page show a clear hero area, a few content sections, and a footer. Add a navigation bar that lets me jump between sections on the page. Include some realistic placeholder content so it looks like a real product or portfolio site, and make the design feel current and professional.

If anything needs to be looked up in current docs, go ahead and check online. After you build it, make sure it runs without errors and the page looks good when opened in the browser.
