uniokmit/portfolio ? reverse-engineered prompt

Build me a sleek dark developer portfolio site that looks polished and a little dramatic, with a clean landing page, a projects section, and a short about me area. I want it to feel modern and experimental, with subtle animations, a strong visual style, and an optional immersive WebGL style showcase page that opens only when the user chooses it.

Please make the experience responsive and fast, and keep it friendly on phones and desktop. If you include audio, make it fully user controlled with obvious play and pause controls, and never auto resume or hide the controls. Use the existing assets where they make sense, and keep the main page simple so the portfolio still feels professional. If you need current docs or examples for browser features, look them up online first.
