Modified GradientBlinds effect to be static relative to container on mobile devices (<=768px). This prevents the "ghost drift" effect where the spotlight position shifts during inertia scrolling because the animation loop was updating the target based on scroll offset.

On desktop, the existing behavior (tracking mouse with scroll compensation) is preserved. On mobile, the spotlight updates only on touch/drag events and remains fixed relative to the container during scrolling.

Preserve pointer updates when mouseDampening=0 on mobile

When isMobileRef is true, onPointerMove now clears pointerPosRef. In the render loop, the no‑dampening path (mouseDampening <= 0) only applies mouseTargetRef if pointerPosRef is non‑null, so on mobile the spotlight never updates for users who set mouseDampening to 0. This is a regression from the previous behavior (touch/mouse would still move the spotlight) and will affect any consumer disabling dampening.

Useful? React with 👍 / 👎.
