   establish a new stacking context, so a z-index:-1 child would escape past .product/etc. looking
   for the nearest ancestor that DOES establish one — usually far up the tree — and paint behind the

   makes it a real stacking-context boundary; the fringe's z-index:-1 then resolves locally, painting
