The new code captures animation sequences by writing developer-guide.animations.<title>-frame-*.png files and a manifest for each demo, but the workflow that follows (.github/scripts/compare-animation-screenshots.sh) still diffs every PNG in the storage directory against docs/developer-guide/img. No baseline assets exist for these newly produced frame images, so every run will report “No baseline found for …” and mark the job as failed even though the frames are expected. Either update the comparison script to skip or specially handle *-frame-*.png files (e.g. consult the manifest) or add matching baseline images, otherwise the CI build will consistently fail after this change.
