AI-modified downstream: yes. Create a vertical 2:3 Pinterest composition with commercial-quality art direction: an unbranded pebble-shaped portable power bank rests firmly on a stepped matte plinth, photographed from a confident three-quarter low angle. Use ultraviolet edge light, brushed-silver hardware, warm sand bounce, crisp material detail, and a long sculptural shadow arc on the wall behind it. Grounded architectural still life, premium tech launch mood, restrained props, generous upper negative space. No real brands, no trademarked characters, no watermark, no unintended readable text; omit logos, labels, signage, and interface copy.
