  /* Ownership: Gallery below-the-fold presentation only.
     Shared below-the-fold styles for every Gallery page: the main
     gallery landing (paired with gallery-landing.css for its editorial
     intro and section headers), the artwork-collection pages and the
     artwork-episode pages. Masthead layout, typography and breadcrumbs
     are shared by every pillar/series/season landing page in
     pillar-landing-masthead.css; the collection and episode pages use
     the compact masthead (breadcrumbs only, no hero image), so no
     masthead override is needed here. All card grids (episode/part
     carousels, curated works, part cards) reuse the canonical
     .gnostic-card/.shop-card system from shop.css. */
