How do AI drawings work in a color by number book?

As in Coloring Books: write the theme, "Plan the page ideas" (your AI engine writes a different idea for each AI page, up to 60 at a time; change any of them), then "Draw N pages" (one picture each on your OpenAI or Gemini key). Each drawing is cleaned, its gaps closed, its lines made heavy enough, traced and checked, then colored and numbered. A shaded drawing is drawn once more by itself. "With a background scene" puts each subject in a simple setting that fills the page. Changing the readers or the trim remakes AI pages from the saved pictures at no cost.
