Inventories, Prefixes and Elevators
Inventory-area rules can isolate or switch inventories when players cross configured boundaries, commonly together with Multiverse-Inventories. Prefix areas can change displayed context through supported chat/TAB integrations. Carpet-elevator regions provide vertical travel based on configured carpet/block behavior.
Inventory switching is high risk: back up player inventories and test join, quit, death, teleport and server restart at every boundary. Conflicts usually involve another per-world inventory plugin processing the same transition.
