Build me a simple React app in this repo using the existing Create React App setup.

I want it to run cleanly in development, build without errors, and show a polished starter homepage instead of the default CRA screen. Make it feel like a real modern site, with a clear headline, a short intro section, a couple of nice content blocks, and a responsive layout that looks good on desktop and mobile. Keep the code organized and easy to read, and make sure the page is ready to deploy on Netlify.

If you need to check current React or deployment guidance online, go ahead and do that. Please keep the changes practical and lightweight, and make sure everything works with the standard npm start and npm run build commands.
