Vertical 9:16 video pre-roll frame design. A tall transparent eco-friendly detergent bottle stands centered on a soft fresh green gradient background. A clean splash of clear water arcs around the upper half of the bottle, frozen mid-motion, with a few small droplets suspended in air. A small fresh green leaf is tucked at the base. Soft eucalyptus and sage palette. Upper area shows a small clean centered headline in white serif type reading "Cleaner. Greener. Stronger.". No brand mark on the bottle, no logo, no watermark. Premium eco brand advertising design, photorealistic water dynamics, magazine cover quality.
