+  DW Collection Hero — Steve standing rule (2026-06-23): every collection page
+  must have a background "bg" hero image. Renders collection.image as a full-bleed

+  CONTRASTING PANEL (dark scrim panel) so the text stays legible over any image.
+  Collections with no image fall back to a branded gradient so the page is never
