/* =====================================================
   HUB SUB-PAGE NAV — {{hub_subnav_html}}
   =====================================================
   Contextual, scrollable link bar shown at the top of a
   country hub page (/en/country/:code) or category hub page
   (/en/category/:slug) content, listing that specific hub's
   published seo_pages sub-pages (country_custom /
   category_country — migration 0019), auto-populated via
   0021_hub_subpage_nav.sql and manually manageable from the
   Navigation admin screen afterwards.

   Deliberately a separate component/class namespace from
   .pagenav (the global, site-wide Page Navigation in
   pagenav.css) — this bar is scoped to one specific hub page
   only and does not participate in pagenav-ajax.js. Same
   visual language (theme tokens, scroll mechanics) for
   consistency, on purpose.
