Spine 3.8.99

Before the overhaul in version 4.0, the Graph Editor in 3.8.99 was the primary tool for fine-tuning interpolation curves. It gave animators precise control over "ease-in" and "ease-out" functions, ensuring that movements felt organic and weighty rather than robotic. Inverse Kinematics (IK)
