/* Type — one stylesheet.

   The look: warm paper, ink outlines, hard offset shadows, keys that sit
   proud of the page and press down. Light everywhere except the terminal,
   which stays a dark window because that is what a terminal is. Colours are
   paper, ink, one hot red for the caret and the numbers, and a sun yellow
   for whatever you can press.

   The board changes shape with data-kind on #stage; the page changes
   screens with data-screen on <body>: solo, mp (the race lobby), race. */
