/* 1. Design tokens
 *
   Colour pairs here are contrast-checked, because several were not: --text-muted
   at 2.1:1 and the dark-mode accent at 3.6:1 both failed WCAG AA, on small text
   specifically. Values are chosen so that
     - body text clears AAA (7:1)
     - secondary/muted text clears AA for small text (4.5:1)
     - accent-as-link clears AA for small text
     - white-on-footer-purple clears AA
   Keep that in mind when editing: light-mode accent is deliberately darker than
   the brand purple #8540f5 so it survives at 14px; #8540f5 remains the large
   accent/border colour where 3:1 is enough. */
