The DORS/CLUC 2024 visual uses an optimized WebP derived from a transparent cutout derived from the repository `badge.jpg` photo embedded in the open DC2024badge README.

The public badge page, image archive, and API point at a real badge photo with source URL, license basis, attribution, and cutout-processing notes preserved.
