metaltroop/SynKro ? reverse-engineered prompt

Build me a clean React app that starts from this Vite TypeScript template and turns it into a polished starter site.

I want a simple modern homepage with a nice hero section, a short features area, and a clear call to action. Make it responsive, easy to read, and good looking on desktop and mobile. Use placeholder content where needed, but keep the design professional and minimal. If it helps, add a basic navigation bar and footer too.

Please organize the code in a way that is easy to extend later, keep the TypeScript types tidy, and make sure the app runs cleanly with the existing setup. Use sensible styling and avoid unnecessary complexity. If you need to check current docs online for anything, feel free to do that.
