I've created artifacts/image.png: a PNG, 512 × 512, 8-bit RGB. Checking the format with imd-media ffprobe failed because ffprobe isn't installed (ENOENT), so I used file instead, which reported "PNG image data, 512 x 512, 8-bit/color RGB, non-interlaced". The image is still untracked, as required (git's global ignore rules already exclude artifacts/).

How it was made: I didn't use the image-generation tool. Instead, scripts/gen_iu_0264.py (standard-library Python, since Pillow isn't installed) draws the character pixel by pixel on a 32 × 32 grid, then scales it up 16× with nearest-neighbour. That guarantees square pixels, no anti-aliasing and no gradients. I looked at the render after each of two passes and fixed the eyes, which first read like glasses and had gaps in their outlines.

What the image shows: one front-facing bug bust, centered, with the shoulders running off the bottom edge.

• Head: swamp #7cc84a with flat moss shading and a moss stripe on the forehead.
• Face: two big bone eyes with black pupils and highlights, bubblegum cheeks and a small smile.
• Antenna: two moss stalks with phosphor tips.
• UI tee: cobalt with navy sleeves, black collar and seams, and a tiny bone "UI" logo, the only lettering in the image.
• Outline and background: a thick black outline around every shape, on solid #0c1610 with 5 small moss specks. No scenery, frame or border.

Requirements possibly not fully met:

• The outlines and pupils are pure black (#000000), which isn't in the listed palette. The brief asks for black outlines, so I treated it as allowed.
• I haven't compared it against the other 786 pieces in the set, so whether it matches the collection is unchecked. A visual review is still worth doing.

The generator and a README.md describing the result and these limits are committed. The repo had no git identity configured, so the commit uses Morgan / mo4b@proton.me, set for that one command only.
