Antariksa3/neurogrip-web ? reverse-engineered prompt

Build me a clean, modern web app for Neurogrip.

I want it to feel polished and easy to use, with a responsive layout that looks good on desktop and mobile. Start with a strong landing page, simple navigation, and a few clear sections that explain what the product is and what people can do with it. Make the whole thing look professional, smooth, and consistent, with nice spacing, readable text, and good visual hierarchy.

If it makes sense, include basic interactive parts like buttons, cards, and simple forms or inputs so the site feels like a real product instead of just a static page. Keep the code organized and easy to follow, and use current best practices for a modern JavaScript web app. If you need to look up current docs online while building, go ahead.
