/* Catodoro - the pieces every page shares.

   Loaded first, so each page's own stylesheet can override. Two things live
   here: the footer's contents, and the key chip. The guide turns the same
   footer into a slide-up panel in styles.css; the document pages let it sit
   at the end of the page. Only the positioning differs - everything inside
   is this file, so the two can't drift apart the way the navbar did. */

/* Two weights, three colours, and that is the whole scale.

   Quicksand's 400 goes thin and wiry at reading sizes, so prose sits at 500
   and emphasis inside it at 700 - never a third step. Interface labels the
   eye jumps to rather than reads - nav items, buttons, links - take the 700
   as well. The rest of the hierarchy is colour: ink for the thing being
   named, grey for the explanation around it, paler still for labels. */
