/* Hub pages: category hubs, section landings, tag hubs, author pages and the
   blog index (generated by _build/gen_hubs.py). Rendered inside the article
   template (#content, col-sm-7), so everything here is scoped to the card
   grid and the small chrome around it. Colours come from the brand tokens
   (--brand-*) and the design-system tokens (--c-*) that css/main.css defines
   for light and dark; no new fonts. */
