Every screen was built through Stitch’s streaming agent by describing what I wanted, watching it generate live, correcting through the agent. For all screens, I used variants to explore different art directions. DESIGN.md captured the emergent design system; I exported and re-imported it for consistency. I then prototyped in Play Mode, then exported to AI Studio and deployed on Cloud Run. Features used: Streaming Agent, Agent Manager, Variants, DESIGN.md Export/Import, Play Mode, Code Export.
