Generate only the top hand overlay for a 2D rehabilitation game. The hand is viewed from above, palm facing down, as if it is gripping a ball underneath it. Do not draw the ball. The hand should be a simple white glove-like shape with a clean blue outline. Fingers should be simplified and rounded, slightly curved as if wrapping around a sphere. The center of the hand should cover the imaginary ball. Minimal flat vector style, SVG-friendly, no background, no shadow, no black outline, no realistic anatomy.

The image shows a black and white drawing of a handprint on a white background. The handprint is in the center of the image and is surrounded by a black outline. The background is a solid white color.
