Wireframe Mobile Flow

A lo-fi mobile app flow wireframe — three to four phone frames in a row (onboarding → home feed → item detail → confirm), greybox content inside each device, dashed connector arrows with numbered step labels, and sticky-note annotations. Use when the brief asks for "mobile wireframe", "app flow", "user flow", "lo-fi mobile", "low fidelity", "移动端线框", or "App 流程图".
