    Interface EventContext

    Context object providing access to shared state for event handlers. This is passed to each handler module to avoid circular dependencies.

    interface EventContext {
        activePointers: Map<number, { x: number; y: number }>;
        capturedPointerId: number;
        el: HTMLCanvasElement;
        hasTouch: boolean;
