Created artifacts/logo.png with the built-in image generator. It’s an opaque 1254×1254 PNG. At 32 pixels, the centered gold ingot remains legible and fits inside the circular crop.

Three drafts were drawn. I kept the third; the first two weren’t kept because their tool responses didn’t provide previewable images, so I couldn’t check their small-size readability.

Final prompt: “One single bold gold bullion ingot, simple broad trapezoidal bar with a few large facets, centered on an opaque deep navy background. Keep it readable at 32 pixels and inside the central circle. No text, symbols, extra objects, tiny details, border, frame, margin, or transparency.”
