Black Rectangle Shape Design

A simple yet elegant design featuring a smooth, rounded grey rectangle. The surface of the rectangle subtly transitions from a darker shade of grey on the left to a lighter grey on the right, creating a gentle gradient effect. This modern element is set against a solid black background, highlighting its clean lines and minimalist aesthetic. It evokes the look of a sleek digital button or a foundational UI element.
