Create an elegant premium ice cream cup mockup advertisement in a clean luxury studio product photography style. Show a realistic branded paper ice cream cup as the hero product, centered on a minimal cream display pedestal. The cup should be filled with a tall creamy vanilla soft-serve swirl rising above the rim, topped with rich glossy chocolate drizzle flowing naturally over the swirl and colorful rainbow sprinkles scattered beautifully across the cream. Make the ice cream look smooth, fresh, appetizing, and realistic. Use a soft beige-to-cream gradient studio background with subtle spotlight lighting, elegant shadows, faint marble surface reflection, and a polished commercial advertising finish. The overall mood should feel premium, sweet, clean, modern, and luxurious. Branding style: playful but elegant. Use a fictional brand name: SWIRLJOY Design the cup with a premium cream base, pastel pink, blue, and golden-yellow accents, small sprinkle patterns, soft abstract shapes, and subtle gold details. The logo should be large and clear on the cup, using beautiful friendly typography with a small swirl icon. Make the packaging look professionally designed, realistic, and mockup-ready. Add elegant promotional typography around the product with strong visual hierarchy and clean spacing.
