aniket-pandey-ji/Portfolio ? reverse-engineered prompt

Build me a modern personal portfolio website for Aniket Pandey that feels clean, polished, and developer friendly.

I want a single page site that works great on mobile, tablet, and desktop, with a dark and light mode toggle, smooth scroll animations, a floating social links bar, animated skill progress bars, project cards with hover effects, an achievements timeline, a contact form with basic validation, a scroll to top button, and a subtle preloader. Keep the design simple but impressive, with nice spacing, soft shadows, and a strong first impression.

Use plain HTML, CSS, and JavaScript, and make it easy to open locally in a browser without any build setup. If you need to look up current docs or best practices for any libraries, go ahead and do that. Include the resume PDF somewhere sensible in the layout and make sure the whole thing feels like a real portfolio that someone could send to recruiters.
