Photorealistic vertical 9:16, bright modern kitchen, cheerful UGC look. A happy young girl (about 7-8, generic original child) stands at the counter holding the colorful gradient sport water bottle from the reference image — frosted yellow-to-green-to-purple body with a motivational time-marker scale and a purple flip-top lid. On the counter beside her are a few plain generic unbranded soda cans, each crossed out with a big red X. She smiles, choosing the water bottle over soda. Clean bright modern kitchen, daylight, authentic phone-camera look, shallow depth of field. Keep the bottle exactly like the reference. No brand logos, no on-screen text, no watermark.
