    "prompt": " Full-page illustration of a brightly lit “Geometria City Arena” with a central ring like a boxing/MMA octagon, but the fighters are anthropomorphised shapes: two matte, no-nonsense squares (simple faces, calm eyes, perfectly crisp 90° corners) facing three glossy, overconfident cubes (smirking faces, flashy sponsor decals). The squares stand in tight formation; one cube is mid-stumble, another looks shocked. Crowd is a sea of other shapes holding foam fingers and tiny protractors; overhead screens read “FLATPACK FURY.” Lighting dramatic, sports-photography feel, dynamic perspective from ringside.  "
