/* Eva's & Max's Aeroplane – page layout, screens and buttons.
   Same family look as the other Eva's & Max's games (see ../BRAND.md):
   Fredoka, chunky rounded buttons with a solid bottom edge, the ink and
   toy-box colours below. The window view (#scene) is the top part, the cockpit (css/cockpit.css) the rest. */
