How this workflow runs
Inside the workflow
What happens at each step
Render
Compose the line-art prompt and call the image model.
Post-process
Threshold, seal contour gaps, raise strokes to the print floor, despeckle.
Audit
Measure stroke weight, grey, margin ink, gaps and tappable regions; fail what would not print or fill.
Text gate
OCR the page against its text contract: exact lettering on a facts page, none on an art page.
Classify
Produce catalog metadata.
