/* Begambeli Radio
   ----------------------------------------------------------------------------
   A photograph, and glass floating on top of it. Everything that is not the
   photograph or the video is a frosted panel: white type, pill shapes, system
   font, one warm gradient. The station's own colour — bougainvillea magenta,
   which is what begambeli means — is the live dot and the hot end of that
   gradient, and it is the only hue that carries meaning.
