Create a minimalist commercial advertisement featuring an oversized Subway sandwich as the hero product in an ultra-clean, luxury campaign style. A young woman dressed in an elegant all-white outfit leans casually against the giant sandwich in a relaxed yet confident pose, eyes gently closed, while holding a freshly made Subway sandwich in one hand. The composition is modern and editorial, emphasizing scale, freshness, and visual impact. Use a soft gradient green-to-yellow background with large bold white “SUBWAY” typography placed prominently behind the subject. Include a glossy reflective floor that subtly mirrors the sandwich and the model, enhanced with soft studio lighting and premium food photography aesthetics. Ensure the sandwich appears hyper-realistic, packed with fresh crisp lettuce, sliced tomatoes, cucumbers, onions, cheese, savory meat or veggie filling, signature sauces, and artisan bread with mouthwatering texture and detail. Maintain a clean, luxurious layout with balanced negative space and a sophisticated commercial look suitable for a high-end global advertising campaign. Add small text in the top-right corner reading “Designed by M”. At the bottom center, place the tagline in small white font: “Freshly made. Delicious in every bite.”
