/* Habit Guard website.
   A sibling of the Eye Tracker site: the same dark ground and system type, a strip of
   colour bars, and one signal colour. Here the bars are the four habit colours (nail
   biting, mustache, brows and hair, face touching, the same colours the app draws its
   zones in) and the signal is the app icon's teal, used only where something is
   selected, watched or primary.
   Text uses the visitor's own system face. No web fonts, nothing loaded from other
   sites. */
