/* =========================================================
   Best Ever Medical — Events & News Hub Page
   Loads ONLY on the Page containing [bem_events_news_hub] (see
   functions.php). Depends on custom.css for :root variables, header,
   footer, .inner-hero (this page's own hero — no unique hero CSS
   needed here), and the shared .article-card family (base rules
   shared with the single Event template's "Further Reading" grid —
   only this page's featured/regular grid context values live here).

   ARCHITECTURE NOTE: the static reference filters/shows articles
   entirely client-side (all articles pre-rendered in the DOM, JS
   toggles visibility) with decorative, non-functional pagination
   links. That doesn't scale once the client is regularly publishing
   real articles — eventually every single one would load on every
   visit regardless of filter or page. This build uses real
   server-side pagination and taxonomy filtering instead (via
   ?category=slug&paged=N query args on the same Page), so filter tabs
   and page numbers are real links, not JS state. See
   bem_events_news_hub_shortcode() in functions.php.
