  "prompt": "A refined editorial still-life product photograph, straight-on view, wide landscape composition, warm ivory background. A matte terracotta ceramic vase with a short neck stands on the left third of a pale stone shelf. One bright yellow lemon sits on the right third of the shelf. A small deep green leaf lies flat near the center. Soft afternoon sunlight from the upper left, long subtle shadows, tactile natural materials, plenty of empty space between the three objects. No text, no labels, no people. The entire vase and lemon are fully visible.",
