I've drawn the image and saved it as artifacts/image.png: a 512 × 512 PNG showing a cobalt frog with big eyes, a cap and a suit.

I drew it pixel by pixel with a Python script (tools/draw_iu_0371.py) rather than an image generator, so the style rules hold exactly. It's built on a 32 × 32 grid and scaled up 16× with hard pixel edges. I checked that every 16 × 16 block is a single solid colour, so there's no anti-aliasing, gradient or blur.

• Character: one frog, facing front and centred, with cobalt (#6f7fe0) skin. It has big bulging eyes, a brick-red cap with a brim and a gold button on top, pink cheeks and a wide smile.
• Outfit: a navy suit with a white collar, a red tie, gold buttons and a lilac pocket square. The shoulders run off the bottom edge.
• Outline and background: every shape has a black outline. The background is solid #0c1610 with five tiny green specks.
• Palette: the image uses 10 colours: the background, black, and eight from the allowed list (bone, cobalt, brick, gold, navy, bubblegum, lilac, moss).
• No text: there are no letters, logo, frame or border.

artifacts/README.md records the size, format, palette and the points that are only partly met:

• The cap brim slightly covers the inner top corner of each eye.
• Black isn't on the 14-colour list, but the brief asks for black outlines.
• I only looked at the image myself. Nobody has compared it with the rest of the 787-piece set, so whether it fits the collection is unconfirmed.

I haven't committed anything. The image is left untracked as instructed, and the drawing script and README are untracked too.
