/* ==========================================================================
   JDT Engineering — visual system
   Everything here derives from the logo: two translucent lenses, one cyan and
   one pink, overlapping into violet, with near-black letterforms. The lenses
   only read on a light ground, so the site is built on paper, not ink. The
   overlap tone carries interaction, and the three-stop "spectrum rule" is the
   one repeated device.
