I want to design a TikTok live stream overlay layout. The top half should have a stylish box for the camera, leaving a small space underneath for a text area. Below the text area, create another stylish box for the game display. Keep the boxes simple and sleek with a modern, clean look. The rest of the background should be white so that I can cut out the boxes and add my camera and stream content later. The design should be optimized for a vertical phone screen." This request should guide the AI to create a layout with the specific boxes and white background, making it easy for you to add your camera and game content later
