itsramananshul/Portfolio ? reverse-engineered prompt

Build me a personal portfolio site for a CS student and security builder, with a clean, minimal, fully dark look.

I want a fixed sidebar navigation that highlights the current section as I scroll, and the page should feel like a set of full screen sections instead of one long wall of text. Use a refined editorial style with a nice serif font for headings and a simple sans font for everything else. The design should be responsive, so on mobile the sidebar turns into something more compact and still works well.

Include sections for a hero intro, about me, experience, projects, skills, education, and contact. The hero should show a short intro plus a few quick stats like GPA, project count, scholarships, and tennis ranking. The projects area should show around 10 projects with expandable details. Add subtle animations when content appears and animated skill bars. Make the contact area include email, LinkedIn, GitHub, and a resume download link. If you need to look up current docs online, go for it.
