Zone.Targets (TargetingIndex) answers Within and best-first Best over ITargetProvider regions. EntityTargets offers the observer's VisibleEntities; BeltTargets keys each belt's rocks into kinetic bands and bounds each segment's annular sector for distance, bearing and visibility. Entity.VisibleChunksInReach queries the index with DetectionReachPerVisibility, an upper bound from the sensors' hull. Zone.ChunksNear and AsteroidBelt.InnerRadius are deleted.
