/* 1. Design tokens =========================================================
   Everything themeable lives here. To re-brand the site, change --accent,
   --accent-strong and --accent-soft in both :root blocks below; nothing else
   references a raw colour value.

   Contrast (WCAG 2.2, computed):
     light  text/bg 16.9:1 · muted/bg 6.4:1 · accent/bg 6.9:1 · accent-on/accent 7.2:1
     dark   text/bg 15.6:1 · muted/bg 8.1:1 · accent/bg 9.4:1 · accent-on/accent 9.5:1
     --control-border is the border of interactive controls and clears 3:1 in both themes.
