priyanshu112c/Nova ? reverse-engineered prompt

Build me a polished single page website called Nova that feels modern and clean, using the files in this project.

I want it to open in the browser as a nice looking interactive page, with smooth styling, a strong first impression, and any simple JavaScript interactions that make it feel alive. Make sure the layout works well on desktop and mobile, and that the page looks finished, not like a rough demo. If anything in the current files is incomplete or broken, fix it and wire everything together so the site runs properly from the main page.

Please keep the design tasteful and easy to read, and use the existing HTML, CSS, and JavaScript rather than rebuilding everything from scratch. If you need current browser or web standards info, look it up online first.
