/* Accessible Stores website styles.
   Colours have jobs: highlighter yellow always means "problem", teal and mint always mean
   "fixed" or "do this". Colour pairs used for text (WCAG contrast ratio, AA needs 4.5 for body text):
     ink on white 15.6 · ink on mist 14.0 · muted on mist 7.6 · teal on white 5.1 · teal on mist 4.6
     white on teal 5.1 · white on teal-dark 6.9 · ink on highlighter 11.0 · ink on mint 8.5
     white on ink 15.6 · mint on ink 8.5 · fog on ink 9.1
   The highlighter yellow is only 1.4 against white, so it is never used on its own on white:
   focus styles always pair it with an ink edge. */
