/* Mapleway interface.

   Three fixed themes, chosen with the picker in the top bar and remembered in
   this browser. Every colour is a token below; nothing further down names a
   colour of its own. Flat surfaces, one-pixel borders, no decorative
   gradients, no shadows, no blur: the page is a tool and reads like one.
   Status colours are pale backgrounds with dark text so they stay quiet. */
