1. 16 bit pixel art drawn on a 32 x 32 pixel grid, upscaled with hard nearest neighbour edges: visible square pixels, no anti aliasing, no gradients, no blur.
2. Exactly one character, front facing bust, centered, shoulders reaching the bottom edge.
3. Thick black outline around every shape.
4. Solid very dark background #0c1610 (a few tiny green specks allowed). No scenery.

6. No text, letters, numbers, signature, watermark, frame or border. Only exception: a tiny U plus I logo on a UI TEE.
7. Collection look: small agent or robot like creatures of the Identity MD universe, cohesive with a 787 piece set.
