Implements physics-based rotation that responds to where the user grabs
the card. When you grab a card off-center and drag it, it rotates
naturally based on the grab point and drag direction.
Features:
- Calculate grab offset from card center on pointer down
- Apply rotation using cross product of grab offset and drag direction
- Rotation clamped to ±45° to prevent excessive spinning
- Final rotation preserved when card is released
- Console logging for grab point coordinates and rotation changes
Physics details:
- Cross product (grabOffset.x * deltaY - grabOffset.y * deltaX) determines
rotation direction and magnitude
- Grabbing left side + dragging right = clockwise rotation
- Grabbing right side + dragging left = counter-clockwise rotation
- Scale factor of 5000 provides smooth, realistic rotation feel
