Draw a hand-drawn-style diagram to align with a human on structure — state machines, flows, request paths, component maps, lifecycles. Use when a textual explanation would be easier to judge as a rough sketch, when the user asks for a diagram / 図 / ぽんち絵, or when you want a human to see and approve the shape of a design before you commit to it. Renders entirely on the local machine (no network), with a live browser view the human can watch.
