/* ------------------------------------------------------------------
   CONCEPT: two-tone-glass. Ink on paper, two colours for light.
   Satoshi says it, Zodiak answers, Russo One is the wordmark only.
   Text is black. Backgrounds are white. Colour is light: it lives in
   glass (the hero), in progress (the bar, the nav line) and in the
   closing band. Nothing here is grey.
