wcruzat-web/Cruzat_MERNStack ? reverse-engineered prompt

Build me a clean React app using Vite for a MERN stack project called Cruzat. I want a simple modern frontend that looks like a real production starter, with a homepage, a navigation bar, a hero section, and a few content sections that make the app feel polished and easy to extend later.

Make it responsive, easy to read, and nicely styled so it works well on desktop and mobile. Use reusable components where it makes sense, keep the code organized, and make sure the app runs smoothly with the default React setup. If you need to check the current best practices or docs, look them up online.

I am not asking for a huge backend right now, just a solid frontend foundation that I can build on for a full MERN app later.
