/* Code-block syntax colours, themed through variables so light and dark share
   one set of rules (the values live in custom.css next to the page colours).
   Token classes are pandoc's Skylighting short names. Replaces the per-style
   <style> block pandoc emits, which this site's template never included, so
   fenced code used to render uncoloured. Every light/dark pair is >= 5.9:1 /
   >= 7:1 against its background (WCAG AA needs 4.5:1). */
