/* CHARON — instrument panel, not a casino.
   The subject is somebody's money being at risk. The visual language is a precision
   instrument: dark ground, one warm accent used only for danger, numbers given room.
   Motion is used where it carries information (the cascade actually happened that way)
   and nowhere else. */
