A square commercial campaign image of one unbranded clear cup filled with layered espresso tonic, geometric ice cubes, lively carbonation and a thin citrus peel. Freeze a controlled splash arc around the cup with high-speed product photography. Place it on a sunlit cream stone surface against a translucent pale-blue studio backdrop. Centered hero composition with the full cup visible and generous clean margins, hard summer sunlight creating crisp caustics, condensation beads and sparkling energy. Physically plausible liquid and ice, clean vessel rim, no brand, no label, no extra cup, no text, no watermark.
