The image is at artifacts/image.png. It's a 512 × 512 RGB PNG, 3,866 bytes. I checked the PNG signature and header size with a short Python script. ffprobe isn't installed here, so imd-media couldn't probe the file. I also looked at the rendered image.

What it shows: a front-facing brick (#df523e) frog bust, centred, with big bone-white eyes, black pupils with highlights, pink cheeks and a wide smile. Steel headphones run over the head, with navy ear cups and green (phosphor) LEDs. It wears a cobalt tee with a navy collar and a tiny bone "UI" logo, and its shoulders reach the bottom edge. Every shape has a black outline, and the background is solid #0c1610 with six small moss-green specks. There is no other text or border.

How it was made: I placed every pixel by hand on a 32 × 32 grid in src/draw_iu0510.py, which writes the PNG using only Python's standard library. It enlarges the grid 16× with hard square edges, so there's no anti-aliasing, gradient or blur, and every colour comes from the allowed palette plus black and the background colour. I did not use the installed image-generation tool, because drawing by hand guarantees the exact grid and palette.

Requirements not fully met:

• The art uses flat colours with no shading, so it's simpler than typical 16-bit pixel art.
• The outlines are one grid pixel wide (16 px in the final image). That reads as thick at full size but is a standard thin outline on the 32 × 32 grid.
• No one has approved it visually, and I haven't compared it against the rest of the 787-piece set.

I committed README.md (which records these details) and the script. The image itself is untracked, since the repo's local Git exclude file (.git/info/exclude) already ignores artifacts/. Git had no author identity set, so I used charlietkh / charlietkh@gmail.com for that one commit and didn't change any Git settings.
