Ultra-realistic social media poster of a gourmet double cheeseburger, perfectly stacked with fresh lettuce, tomato, onions, and melted cheese. The burger sits on a reflective tabletop with soft cinematic lighting and realistic textures of bun, meat, and toppings. Include floating ingredients like sesame seeds, tomato slices, and subtle seasoning particles in motion. Vibrant gradient background (orange-red), slight depth-of-field to emphasize the burger. Integrated text placeholders for ‘50% OFF’, brand logo, and call-to-action. High-resolution, hyper-realistic, editorial-style for Instagram or Facebook advertising
