I made artifacts/image.png: a 512 × 512 PNG (8-bit RGB) of IU_0546, a gold bot wearing shades and armor. I checked the file header and dimensions and looked at the rendered image myself; nobody else has reviewed it.

How it was made: I placed every pixel by hand on a 32 × 32 grid in a small Python script (tools/iu_0546.py, standard library only), then scaled it up 16× with hard pixel edges. I didn't use an AI image tool, so each pixel is exactly one of the listed colours, with no blur, gradients or soft edges.

What it shows:

• One robot bust, facing front and centred. The head is gold with flat tangerine shading and bone highlights, and there is a phosphor-green antenna bulb.
• Black-framed navy sunglasses with small lagoon-blue glints.
• No headgear. The antenna counts as part of the bot's body.
• Steel armor with navy shading, shoulder plates and a glowing phosphor chest piece. The shoulders run off the bottom and sides of the image.
• A thick black outline around every shape, and a solid #0c1610 background with six small moss-green specks. There is no text, frame or border.

Things to know (also listed in README.md):

• The outline is pure black (#000000). The brief asks for black outlines, but black isn't in the listed palette.
• The sprite is mirrored left to right, so highlights appear on both sides rather than coming from one light direction.
• Each background speck is one grid pixel, which is 16 × 16 pixels at full size.
• I haven't compared it against the rest of the 787-piece set, so someone should check it fits the collection.

I committed the script and README. The image itself is uncommitted, as required. Git ignores the artifacts/ folder because of a local exclude rule I didn't add. Git had no author name set up, so I used your name and email for that one commit only. I didn't change any git settings.
