/* ==========================================================================
   Zlatara Smaragd
   Ground: the shop's own brand emerald (#012C23, sampled from their logo card).
   Objects: product photography shot on pale marble, lit like a vitrine.
   Signature: the emerald cut — every image sits in a beveled-corner window
   with a hairline gold frame; the hero window carries the full step cut.
