//:: mw_hall_enter -- Hall of Legends OnEnter handler.
//::
//:: When a PC enters, for each guide the PC has unlocked: if the live
//:: NPC isn't yet spawned, destroy the placeholder statue and spawn the
//:: world-form creature at the statue's location. The swap is permanent
//:: server-side (next PC sees the live guide) -- acceptable for a public
//:: hub area.

//:: Failsafe: if another PC is already present (missed gate, reconnect after
//:: logout, future entrance without occupancy check), the entrant is ejected
//:: to the Well of Eru without disturbing the room state.
