/* ============================================================
   Tektome — Resources hub page (resources.html).
   One destination that aggregates every Resources article:
   News, Blog, White Papers, and FAQ.

   The page hosts THREE interchangeable layouts, switched via the
   "Layout" tweak (data-layout on .rhub-stage):
     • editorial  — featured lead + per-category lanes (default)
     • feed       — filter chips + one mixed grid of everything
     • directory  — category portal tiles + a dense latest list

   Loaded after nav.css, button.css, and news.css so it can reuse
   the shared hero band (.news-hero), brand media tiles
   (.news-media--*), category pills (.news-pill--*), CTA strip
   (.news-cta), and .card-title-link. Tokens come from
   design-system/colors_and_type.css.
