"prompt": "Close-up, top-down view of a teenage girl lying on a vibrant picnic blanket spread out on the green lawn of a sunny backyard garden. She’s laughing joyfully as a playful puppy stands beside her head, licking her ear. Her eyes are closed from laughter, and her expression is full of pure delight. The blanket is colorful — with bright patterns like florals or stripes — contrasting against the lush grass. Around them, soft natural sunlight filters through tree leaves, casting dappled shadows and warm highlights across her face, hair, and the puppy’s fur. Flowers, garden plants, or scattered toys add playful detail in the background. A lively, heartwarming outdoor moment filled with summer energy and color.",
