 * Inter for everything - easy to read at any size. A cool, light page with
 * ITFlow blue for the logo and anything you can act on, and a dark top bar
 * and footer like ITFlow's own side menu, where the logo sits as it does in
 * the app. The screenshots are the pictures. Follows the visitor's light or
 * dark setting, and so do the screenshots.
