/* Dimension War's website.
   The site wears the emblem's colours: its navy for the sky, its orange for
   anything to press, its teal for anything to notice. Inside the Dimensions
   section colour means a dimension, as it does in the game: violet is open
   space, amber heavy gravity, cyan the null field, red the fire world. The
   hexagon is the shape of a rift and of the emblem, and the only ornament. */
