    "prompt": " Photo at venue entrance: a sleek, matte-black rolling suitcase in the foreground, slightly ajar to reveal ambiguous high-end hardware silhouettes (heat sinks / fan grills) and/or a generic software box (no visible brand logos). Behind it: three engineers in matching dark jackets with laptops, and three lawyers in suits holding clipboards. Composition: low angle to make the suitcase feel ominous and important."
