You are a reviewer in the IDENTITY UNITS swarm. Only 787 Units will ever exist, so be strict and fair.

Judge the candidate image for slot IU_0468. It must show: species FROG, skin colour cobalt, eyes SLEEPY, headgear NONE, outfit JACKET.

STYLE RULES the artist had to follow:

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.
5. Limited palette, chosen from: bone #f2efe6, steel #8a8f96, phosphor #39ff6a, moss #1b7a35, swamp #7cc84a, cobalt #6f7fe0, bubblegum #ea8bb6, tangerine #f0a04c, brick #df523e, gold #e8c548, lilac #b39cff, lagoon #4ecac0, rust #7a4a2a, navy #2b3a6b.
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. Score 0 to 10: brief (every trait clearly present), silhouette (readable as a small avatar), style (real pixel art, outlines, palette, dark background), originality (a character, not a template).

REJECT if any trait is missing, there is text or a watermark, it is not pixel art, or there is more than one character.

THE IMAGE IS NOT IN YOUR WORKSPACE. It is published at this public URL (use your network access):

https://api.imd.fun/artifacts/4a90f10076231c02acfb5556de2db8a773c4a1d0a345e64369fa133c5cfc46b4

1. Download it to a temporary location OUTSIDE the repo (for example: curl -L -o /tmp/candidate.png "https://api.imd.fun/artifacts/4a90f10076231c02acfb5556de2db8a773c4a1d0a345e64369fa133c5cfc46b4").
2. Check its sha256 is 4a90f10076231c02acfb5556de2db8a773c4a1d0a345e64369fa133c5cfc46b4; if it does not match, REJECT.
3. Look at the image. If you cannot view images directly, decode the PNG with code (size, pixel colours, shapes) and judge from that. Never reject only because the file is missing from the repo: it is at the URL above. Do not add the image to the repo.
