   Collections Showcase page

   Grid cards (.collection-card) reuse the feature panel's flat
   .collection-feature__image / __overlay / __title / __cta classes directly,
   so both the large feature and the grid stay visually identical — only
   .collection-card's own rules + the two size overrides below differ.
