/* ==========================================================================
   Tepegöz website. The colour of a camera housing at night: blue-graphite
   ground, text in the bone of the paper-cut logo, and no brand accent. The
   only colour on the page is what the cameras see and what Tepegöz marks on
   it: blue for a track, green, amber and red for states. The pictures are
   footage, so they get the camera treatment (grain, vignette, a flatter
   colour) and nothing else does. One theme, on purpose.
