/*
 * Prefill website.
 *
 * Built on the same tokens as the extension, so the site and the product are
 * one brand: a light ground, deep navy as the one strong colour, black text,
 * white on navy, soft rounded corners.
 *
 * Every text pair below was measured before it was written, light and dark:
 *
 *   LIGHT                                   DARK
 *   body text on page      19.77:1          body text on page      19.04:1
 *   body text on card      21.00:1          body text on card      17.07:1
 *   headings on page       14.40:1          headings on page       19.04:1
 *   links on page          10.77:1          links on page           9.96:1
 *   button label on navy   11.44:1          button label on navy   11.44:1
 *   text on deep band      15.29:1          text on deep band      11.44:1
 *   control edge on page    3.39:1          control edge on page    6.37:1
 *
 * Two rules that are not negotiable, both learned the hard way on the
 * extension:
 *
 * 1. No grey text. Body copy, secondary copy and fine print are all black on
 *    light and white on dark. Hierarchy comes from size and weight.
 *
 * 2. Never dark text on a blue button. In dark mode a brighter blue with a
 *    black label would measure 5.63:1 and pass the rules; it is still not
 *    done. Buttons are white on navy in both themes, and in dark mode they get
 *    a light edge so they stand off the near black page.
