Japanese Summer Sports Drink Poster

A photorealistic Japanese summer beverage advertisement poster in a tall vertical layout, designed like an official sports drink campaign. Show a full-body teenage schoolgirl standing outdoors on a sunny hilltop road overlooking a coastal town and the ocean under a vivid blue sky with large white clouds. She is centered slightly left, posed confidently with one leg relaxed, looking off into the distance, holding a clear plastic bottle of drink_brand in her right hand near shoulder height. She wears a classic Japanese sailor school uniform: 1 white short-sleeve sailor blouse, 1 navy sailor collar with white stripes, 1 large navy neckerchief bow, 1 navy pleated skirt to the knees, 2 white knee-high socks, and 2 dark navy or black loafers. Her hair is long, straight, and black with a glossy sheen. Bright midday lighting, crisp shadows, fresh clean atmosphere, high realism, commercial poster finish. Use a strong brand-forward composition. In the top left, place a large bold white logo reading "ION SUPPLY DRINK" above oversized main_logo_text with a white wave shape beneath it. In the top right, add a small white corporate mark and the text company_name. On the right side, set a vertical Japanese headline in dark blue reading headline_text. In the lower left, add a Japanese body copy block in blue, including a larger subheading and several smaller lines of explanatory text, styled like authentic ad copy. Near that text, include 1 white circular information badge with blue Japanese text and 2 small inner circles labeled "水分" and "イオン" joined by a plus sign. At the very bottom left, add small blue recycling-related fine print and iconography; at the bottom right, add the website URL website. Make the overall design feel like a believable premium Japanese poster for a refreshing ion supply drink, suitable as a desktop wallpaper.
