Win Canvas

You Won

The WinCanvas becomes visible when the Player wins. To ensure it always fits the screen and remains centered, its size is updated every frame to match the window dimensions, and its position is recalculated to be in the center of the window on each frame. This allows it to respond dynamically to any window resizing.
