### Description
Rule-based tracking model that determines which hand each player uses. At every release and catch it compares the distance of the ball to the left and right wrist, hand and fingertip keypoints, classifies the action as left, right or two-handed, and reports the counts, the dominant hand, a laterality index and the average release speed achieved with each hand. It also measures the peak wrist speed reached just before every release, as a movement-side indicator of throwing power.

## Execution Profile
This model operates using static or constant calculation layers. No dynamic training pipeline is required for this configuration.
