- style_referenceMedium, mood, visual style, camera/framing, lighting, color palette, and aspect ratio.

Quality checks
- Character design matches the iconic animated game look — not a live-action or photorealistic interpretation
- Dynamic pose with speed-lines is present — not a static standing pose
- Background reads as a colorful game level, not a plain gradient backdrop
