 * All selectors below are unchanged from the original site's index.css — only
 * the custom-property VALUES here, and a handful of literal light backgrounds
 * on the large surfaces (accordion drawers/items, sub-cards, hero, etc.), were
 * adapted so the migrated documentation reads correctly on a dark background.
 * Small semantic accent chips (pills, tags, badges, callouts, status dots)
 * were intentionally left in their original light colors as legible accents.
