Two unit squares are placed side-by-side. A line segment connects the top-left vertex of the left square to the bottom-right vertex of the right square. Another line segment connects the top-right vertex of the left square to the bottom-left vertex of the left square. Let $C$ be the intersection point of these two segments. What is the area of the triangle formed by point $C$, the top-right vertex of the left square, and the bottom-right vertex of the left square?
