Nested Picture-in-Picture Software UI

生成一张具有视觉纵深感的‘画中画’图像。最外层是一个真实的 编程界面，中间嵌套一个应用名称的聊天界面，聊天界面里我正在发送一条消息，内容是‘生成请求’。千问回复了一张精美的咖啡海报，这张海报也清晰地显示在聊天界面中。要求每一层UI都保持真实的风格与细节，界面中的时间数字、按钮小字等微观细节清晰可辨。

Generate a 'picture-in-picture' image with visual depth. The outermost layer is a realistic programming interface, nested with a app name chat interface. In the chat, I am sending a message saying: 'request content'. 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.
