Nested Picture-in-Picture Software UI

Generate a 'picture-in-picture' image with visual depth. The outermost layer is a realistic VSCode programming interface, nested with a Qwen App chat interface. In the chat, I am sending a message saying: 'help me generate a hand-brewed coffee poster'. The app replies with an exquisite coffee poster, which is also clearly displayed in the chat interface. Each UI layer must maintain realistic style and detail, with clear micro-details like time digits and button text.
