I've finished the image: artifacts/image.png is a 512 × 512 PNG (RGB, 10 colours). I didn't commit the source files, because git has no author name or email set up here and I didn't want to change the git config myself.

How it was made: a Python script draws the character on a 32 × 32 grid, then scales it up 16× with nearest-neighbour. That keeps the square pixels hard-edged, with no anti-aliasing, gradients or blur. I checked the output once: 512 × 512, PNG, 10 colours. I also looked at the picture once myself; nobody else has reviewed it.

What the image shows:

• A front-facing robot bust, centred, with a lagoon (#4ecac0) head.
• Black 2×2 dot eyes, grey ear bolts and neck, pink cheeks, a white shine, and nothing on its head.
• A navy jacket with blue lapels over a white shirt, with the shoulders running off the bottom edge.
• Thick black outlines around every shape.
• Background #0c1610 with a few small green specks.
• No text, frame or border.

Requirements: I know of none that aren't met. The only thing to flag is that the outline black (#000000) isn't in the listed palette, but the "thick black outline" rule requires it.

Other files:

• tools/draw_iu_0516.py is the script that draws the image; run python3 tools/draw_iu_0516.py from the repo root to rebuild it.
• README.md gives the size, format and colours used, and notes on the requirements.

Both files exist but aren't committed. The image is untracked, as the task asks.
