Design a simple 2D vector game asset of a coffee cup icon. The cup should have a smooth, rounded shape with a light brown color for the body and a darker shade for the handle. A small, white swirl on top represents steam, giving it a warm, inviting feel. The background should be a solid color, such as soft beige, to keep the focus on the cup. Use bold outlines and minimal details to ensure the design is straightforward and easy to vectorize for later animation.
