      "prompt": "Use case: photorealistic-natural. The reference is the exact ROWAN Nova Reverie espresso machine; preserve its two-cylinder design if it appears. Create a wide 16:9 premium editorial photograph of a home coffee moment in soft morning light. A single empty-looking large 250 ml transparent double-wall cylindrical drinking glass WITHOUT a handle holds a small freshly brewed espresso at the bottom, approximately 40 ml, with delicate crema. The same glass will later be edited into Americano and latte, so choose a generous straight cylindrical shape with a clear rim and a thick double-wall base. Put the glass center precisely around x=65% y=65%, its height about 28% of image height; table contact at y=81%. Warm pale stone countertop, softly blurred modern neutral home interior. The real ROWAN machine from reference is in the far right background, partly cropped and softly out of focus, recognizable but never more prominent than the cup. Camera at just above glass rim height, 70mm lens appearance, natural realistic depth of field. Window morning light enters from right, subtle warm highlights on crema and glass, elegant delicate shadows. Keep left third calm and naturally shadowed dark warm gray, clean negative space for white website copy. No plants, no pastries, no cloth, no spoon, no milk pitcher, no person or hands, no artificial steam, no typography, no watermark. Glass position and whole setting must be stable for later liquid-only edits. Real attainable coffee and natural materials, luxurious editorial photographic quality, not CGI.",

      "prompt": "Use case: product-mockup. Create a photorealistic 16:9 premium ecommerce packaging-concept still life for ROWAN Nova Reverie. Reference 1 is the exact machine: strictly preserve twin silver suspended cylinders, clear grinder hopper, black angled tamp lever, circular black top controls, right-side pressure gauge, original steam wand, slotted base and ROWAN branding. Reference 2 is the official accessory assortment. Scene: seamless soft pale-gray studio floor and background, beautiful broad diffuse side light and soft grounded shadows. Full machine occupies right half, a simple off-white rigid rectangular shipping/display box behind it slightly left bearing ONLY the small word ROWAN in tasteful gray sans-serif. The box is an explicitly proposed concept, no technical drawings or certification icons. Arrange the exact accessory types from reference 2 neatly in the foreground at right: original black-and-silver portafilter, small stainless milk pitcher, two metal filter baskets, metal cup riser, narrow brushes and cleaning pin, folded orange microfiber cloth and a simple small cleaning sachet. Avoid duplicate pitcher or portafilter: the machine should have no installed portafilter and no pitcher on its tray because both are in the accessory layout. Keep product silhouette accurate. Left 30% is mostly empty pale-gray space for webpage headline. The scene feels like refined real product photography, not exploded CGI, no floating items, no glass coffee cup or unrelated accessories. Add one small unobtrusive caption exactly 'PACKAGING CONCEPT' at bottom right, clearly readable gray. No sustainability badges, no certification markings, no warranty claims, no other text or watermark.",
