sahtushar/unicards-replica ? reverse-engineered prompt

Build me a React site that feels like a polished UniCards style replica, with a clean modern landing page, strong typography, and card based sections that look good on desktop and mobile. I want the whole page to feel smooth and professional, with responsive spacing, nice hover states, and styling handled in SCSS.

Please make it work as a normal Create React App project so I can run it with npm start and build it for production. Keep the layout simple but visually close to a real product site, and make sure the design scales well on smaller screens. If anything in the original design is unclear, make a sensible choice and keep going. Use current docs online if you need to.
