   VAPOR common — shared primitives loaded on EVERY page from theme.liquid.
   Holds the design-system pieces that appear in more than one template:
     · vp-card             (home, collection, search, wishlist, related,
                            recently-viewed)
     · vp-fc               (home featured-collection, related-products,
                            recently-viewed)
     · vp-collection-list  (home tiles, /collections list)
     · vp-tile
     · .pagination         (collection, search)
     · .section-title      (page H1 default — sized for page LABELS, not
                            stadium-sized banners)

   Home-only / feature-section styles (image-with-text, testimonials,
   newsletter, multicolumn) live in homepage.css and load only when those
   sections are present.
