This page reads boss state from the live map-server death flow plus the permanent spawn registry, so dynamic maps can still show when a boss is already available even before a player steps onto that map again.
Tracks MVP spawn map, countdown timing, and ready-state even while dynamic maps are asleep.
Keeps Mini Boss entries separate so the list stays clear while still respecting dynamic-map respawn windows.
Available first, then dead entries with respawn timers.
Ready means the respawn window is already open even if the dynamic map is still sleeping.
