/* The document around the page, which no sheet of the design can style: a design's skin names classes, never an element
   alone (SCREEN-13), so the margin of the body and the colour of the canvas are this site's. Every colour is a token the
   design lays; the canvas follows the device as the tokens do, light unless the device prefers dark. */
