An image of a modern and simple design. The overall size of the image is 1024x1024 pixels and is square. A simple frame is placed in the center for adding text, and the color of the frame is set to soft gray to make the text visible. The frame covers 95% of the entire screen. The frame has a soft shadow effect, making the text stand out. Please design the overall feel of the image to be clean and sophisticated, and to match the presentation slide.
