   Apple-flavoured: near-black canvas, one accent used sparingly, very large
   display type with tight tracking, generous air, and depth built from soft
   light rather than hard borders.

   Motion uses a single expo-out curve everywhere. Mixing easing curves is the
   fastest way to make an interface feel assembled from parts instead of
   designed, so there is exactly one.
