Technical content rarely comes with visuals, and stock images would break the style. I drew a set of 20 line-art icons that defined the visual language, then built a generator in Claude Code that extends it. It combines two simple shapes (circle, square, triangle) into one overlapping composition, following strict rules for size, overlap and placement. The generator measures the real shared area and throws out anything that isn't a clear overlap. Every new article or case study gets its own cover in the house style, and no designer is needed.
