ScreenBounds
A screen-space AABB plus a camera-relative depth range, both derived from the same set of world-space bounding points a SceneObject already computes for its frustum check (getPositionsForFrustumCheck) - the broad phase of overlap detection reuses that geometry rather than computing anything new.
