Generate a simple flat vector SVG-style asset for a rehabilitation game. The image should show a full hand from a top view, with the palm facing downward and wrapping around a spherical object. The hand should appear to be gripping the ball naturally. The ball must remain partially visible on the left and right sides, and slightly below the hand, so the grasp is visually clear. Use a white fill for the hand, a medium blue outline, smooth rounded contours, and a clean minimal 2D interface style. The object should be a round ball, and the overall design should match a soft blue-and-white medical therapy game UI. No realism, no background, no shadows or only very subtle ones, isolated centered asset, suitable for SVG export.

The image shows a black and white drawing of a pair of gloves on a white background. The gloves are outlined in black, giving the image a bold and striking look.
