   The visual system is taken from the company mark: a labyrinth of rectangular
   copper traces turning only at right angles. That gives the page its three
   recurring devices - hairline traces with square terminal pads, mitred icon
   strokes, and the magenta-to-indigo gradient the mark is filled with. Nothing
   on the page is rounded by more than 2px, and no line turns at anything other
   than 90 degrees.
