Konwersja szkicu na grafikę liniową w stylu CAD

A two-part prompt sequence for Nano Banana Pro (using its 'Thinking Mode') to convert a rough sketch into precise, CAD-like line art. The first prompt instructs the model to finalize the rough sketch, referencing blue text annotations, removing ambiguity, and applying line weight variation. The second prompt is a follow-up instruction to apply the same style to subsequent rough sketches.
