rdogif/portfoliost1 — reverse-engineered prompt

I want a simple personal portfolio site built from this repo. The main page should feel clean and modern and introduce me and the projects I have here. Please turn the homepage into a portfolio landing page with a short about section, a nice header, and clear project cards or buttons that link into the existing project folders like the blackjack project and the save and load project.

Make it look good on both desktop and phone, with basic styling, smooth navigation, and copy that sounds friendly and polished. If it makes sense, add a short description for each project so a visitor understands what it is before clicking. Keep it lightweight and easy to host as a static site.

If you notice anything missing, just make reasonable choices and keep the structure simple. You can look up current examples of clean portfolio sites online if you need inspiration, but please keep it straightforward and based on what is already in this repo.
