Generate a single original editorial product photograph for SZKIDS prompt library. A matte ivory refillable skincare bottle with NO text and NO logo, a single broad sage leaf behind it, pale travertine cylindrical pedestal, warm cream seamless background, soft window light from upper left, precise soft contact shadow, fine natural surface detail, calm contemporary skincare campaign. Bottle centered in lower two-thirds, generous empty upper third for later headline. Portrait 4:5 composition. No collage, no typography, no watermark. This is the actual example output for a prompt teaching minimalist skincare product photography.
