High-fidelity desktop SaaS UI screenshot for an AI workflow builder product. Landscape 16:10 composition with an icon sidebar on the left, a draggable workflow canvas in the center and a step settings inspector on the right. The canvas includes connected node cards for trigger, research, draft generation, quality check and review notification, with clear connector lines, status dots and small action controls. The inspector shows model selection, tool toggles, output format, temperature slider and a run button. Bright professional style, white and pale gray surfaces, teal and amber accents, restrained spacing and soft shadows. No real brand names, no real logos, no watermark, avoid large readable paragraphs.
