   The artwork is maximal: gold, teal, magenta, cream. So the interface
   deliberately is not. One warm near-neutral ground, no gradients, no
   brand colour in the chrome — the artwork stays the only saturated
   thing on screen.

   The one exception is --cream, used for the writing surface: that is
   the same paper the text lands on, so the writer shows the real ink
   and script rather than an approximation of them.
