Nano Banana Pro X Header Image Generation Prompt (21:6 Aspect Ratio)
A detailed prompt for Nano Banana Pro to generate an X (Twitter) header image. It uses a 21:6 aspect ratio, which is close to the required dimensions, and defines an invisible safe zone to ensure the main face and a custom title logo (based on user text and a style preset) are visible and centered. It includes options for zooming in on the face.
