/* Contact Sheet. A darkroom, not a light room.

   One accent: Kodak yellow-orange, the colour a safelight and a film box share.
   One drawn idea: the film edge, in real 135 geometry, which is the launcher icon,
   the header, the counter chrome, the rule between sections and the empty state.
   One corner language: 3px on controls, 1px on anything that is meant to be film.
   The only other colours in the app are printed on a film box, and a film box is an
   object rather than a control. Light leak orange appears inside drawn film and
   nowhere else. */
