/* The Docs page (/docs, 29 Sep): a sticky sidebar of tabs beside one panel at a time. Every colour is a site token
   (styles.css + fable.css), so both themes work. Sizes follow the rest of the site, which renders desktop at html{zoom:.75}:
   body copy here is 16px, tables 14px, small labels no smaller than 10.5px. Panels are hidden by class, not [hidden], so the
   :target fallback below still switches tabs if docs.js never runs. */
