/* Scriby website.
   One typeface (the app's own book face), the app's warm black and brass, and almost no chrome.
   Every scene is exactly one screen. Type and spacing scale with the viewport HEIGHT as well as the width,
   so nothing is clipped on a short laptop screen. Every scene is written in its finished state;
   site.js animates toward it. */
