+0.1.J decision: the MVP death/respawn loop does not spawn a physical corpse or
+backpack actor yet. Respawn currently stabilizes the character at the Ground
+Zero MVP spawn/home location without inventory-drop recovery. When inventory
+loss is introduced, corpse/backpack records should be persistent, server-owned,

 captures live Agrarian player characters into `FAgrarianSavedPlayer`, including
 transform, survival snapshot, care history snapshot, and inventory stacks.
