amritmotwani357-crypto/aura ? reverse-engineered prompt

Build me a clean, modern React site called Aura for a crypto brand.

I want a polished landing page that feels premium and futuristic, with a strong hero section, a short value proposition, a few feature cards, and a simple call to action. Make it responsive so it looks good on mobile and desktop, and keep the overall style sleek with dark, glowing, crypto inspired visuals.

Use the existing React and Vite setup in this repo, and organize the app so it is easy to extend later. If you need current best practices or a small library choice, look up the latest docs online and use whatever fits best.

Please also make the page actually useful, not just decorative. Include a clean navigation area, some basic sections that explain what Aura does, and make sure the final result runs without errors and looks finished.
