# Image provenance

The backgrounds, feature images and portraits in this directory were
generated with AI in Midjourney, and `screenshot.png` shows them (see the
image credits in `readme.txt`). The Acme logos were made for the theme.

## Machine-readable marking (EU AI Act §50(2) alignment)

The files listed under "AI-generated" carry the IPTC digital source type
marker (`XMP-iptcExt:DigitalSourceType = trainedAlgorithmicMedia`), applied
2026-11-03 after the WebP conversion. `screenshot.png` (in the theme root)
carries `compositeWithTrainedAlgorithmicMedia`, since it is a screenshot of
the theme showing these images.

To tag a newly added AI-generated image:

    exiftool -overwrite_original \
      "-XMP-iptcExt:DigitalSourceType=http://cv.iptc.org/newscodes/digitalsourcetype/trainedAlgorithmicMedia" \
      <file.webp>
