/* Email Preview Tool, direction C ("Gate"): signed like an airport. Sign yellow is kept for wayfinding only:
   the nav band, the screen chain and the count sign. Sign black carries the type on yellow and the pictogram
   squares. A grey concourse holds the phone; white panels hold the writing. Square corners, panels meet at
   rules, no shadows except the device's own. One authored motion: the count flips like a split-flap board. */
