/* =========================================
   KENNISBANK
   Hub + article styling for /pages/kennisbank/.

   Deliberately thin: the article shell reuses the .news-article__*
   component set already in main.css (header banner, lead, dropcap,
   sections, highlight, stats, cta, sidebar, toc, author, share) and
   the hub reuses .news-hub__list + .news-card. Everything below is
   only what those components do not already cover — prose elements
   authored inside scripts/data/guides.mjs (lists, tables, callouts),
   the hub's tag filter, and the related-article grid.

   Mobile-first. Tokens only. No fixed-px layout widths.
