Rig-oriented lighting helpers for repeatable Blender look-development setups.
Use this skill when a scene needs grouped lights, reusable three-point rigs,
HDRI/world setup, fixed-camera rotating-environment LookDev, light aiming, or
render view-transform coordination. Create the world with create_hdri_world,
then use animate_hdri_rotation for a repeatable lighting sweep. Single light
creation and basic property edits remain in blender-lighting.
