The Coinstark logo is at artifacts/logo.png: a 1024×1024 square PNG of a flat gold coin with one bold white lightning bolt, on a solid deep navy background that fills the whole square. There are no words, letters, numbers, frame or border, and the coin sits well inside the central circle. Git doesn't list it, so it stays out of any commit as required.

What drew it: the installed image tool (Replicate), using the black-forest-labs/flux-1.1-pro model. No code drew any part of the picture. The brief didn't include the requester's own description, so the idea comes from the name: a coin, with a lightning bolt for "stark" (strong, striking).

Drafts: I drew 2 and kept the second.

• Draft 1 (not kept): the coin filled only about 45% of the width, and it had fine engraved rings, small rivet dots and a slight 3D edge. Those details would turn to mush at wallet size, and the mark was small.
• Draft 2 (kept): the coin fills about 58% of the width, with a plain face and flat colours, so the shapes stay bold.

Check: I shrank both drafts to 32 pixels and cropped them to a circle, the way a wallet shows a logo. Draft 2 still reads clearly as a gold coin with a white bolt on navy. The bolt is the thinnest part, but it's still clear at that size. I also confirmed all four corners are the navy background, so nothing is transparent or blank. There was no image library on the machine, so I made the preview with a small Python script in test/scratch/, which isn't delivered.
