What is the CSS effect as you enter the page? Are they streaming the CSS itself, or just an animation in the browser? Very cool effect.

It's a CSS animation from the Jekyll theme. Pulled from the minified CSS:

    @keyframes intro {
        0%   { opacity: 0 }
        100% { opacity: 1 }
    }

Applied via:

    animation: intro 0.3s both;
    animation-delay: 0.15s;
