/* ==========================================================================
   home.css — the front page only.

   Two parts. The opening fills the screen with the WebGL tunnel and carries
   the name and the three ways in. Below it, #work is an ordinary page in the
   site's own vocabulary (site.css tokens, .container, .eyebrow), so scrolling
   down lands somewhere that already looks like the apps pages and the CV.
