A full slider is UISlider + Interactable + UIRect (its footprint). RenderSystem draws a filled/empty track split at the thumb plus a circular thumb colored by m_ThumbColor's state. systems::UIInteractionSystem sets m_Value from the pointer's x while the Interactable is held (even off the rect) and fires m_OnValueChanged whenever it changes, including on the initial press.
