RovaIsaia/RovaIsaia.github.io ? reverse-engineered prompt

Build me a clean personal portfolio website for a student in Artificial Intelligence and Astrophysics, with both French and English versions.

I want it to feel professional but still personal, and to clearly introduce me, my skills, my projects, and my achievements. Make it modern, mobile friendly, and easy to browse, with smooth sections for an about me page, skills, project highlights, experience or education, and a contact area. I’d also like a simple way to switch between French and English, plus a contact form that can send messages through a service like Formspree. Use icons and a few polished animations if they help the site feel alive, but keep everything lightweight and responsive.

Please make it ready to host on GitHub Pages, and use plain HTML, CSS, and JavaScript so it’s easy for me to understand and update later. If you need current docs or best practices for any library or setup, look them up online first.
