The image is done: artifacts/image.png is a 512 × 512 PNG showing the bubblegum frog in a cap, shades and hoodie. It is not committed, so the daemon can upload it.

How I made it: I drew it in code with tools/draw_iu_0226.py instead of the image generator, whose own instructions say not to use it for exact pixel grids. The script uses only the Python standard library.

• It is drawn on a 32 × 32 grid, and each grid pixel becomes a 16 × 16 block, so the edges are hard and square.
• Every shape has a black outline one grid pixel (16 px) thick.
• The character is a front-facing bust in the centre, with the shoulders running off the bottom edge.
• The background is a flat #0c1610 with six small moss-green specks. There is no text, frame or scenery.

What I checked: I decoded the PNG with a separate script in test/scratch/.

• It is 512 × 512, 8-bit RGB.
• Every 16 × 16 block is a single colour, so there is no anti-aliasing, gradient or blur.
• It uses 9 colours. Seven come from the task palette: bubblegum, cobalt, navy, lagoon, gold, bone and moss. The other two are the background #0c1610 and black.

Where it falls short or I made a call (also in README.md):

• The outline is pure black #000000. The task asks for a black outline, but black isn't in the listed palette.
• The frog's bulging eyes are hidden under the shades and cap. It reads as a frog from the wide pink head, the wide grin and the nostrils.
• I haven't compared it against the other images in the 787-piece set, so whether it matches their look is untested.

I committed the script and README.md. Git had no author identity on this machine, so I passed your name and email for that one commit without changing any git config.
