Create:
1. A finished steampunk image prompt centered on one clear subject and functional mechanism.
2. A character-scale version and an environment or vehicle version.
3. A mechanical-logic note explaining the power source, moving parts, controls, and scale cues.
4. A negative prompt for decorative gear piles, impossible machinery, plastic materials, excessive smoke, copied designs, text, and logos.
5. Notes on silhouette, material contrast, wear, lighting, steam placement, and depth.
6. An originality and plausibility checklist for generating related images in the same world.

Make every visible mechanism support a purpose; do not create steampunk by attaching random gears to an unrelated object.
