+// The AvatarNametag component adds a plate with scene-provided text above an avatar's nametag,
+// for example to show a rank or a role that the scene assigns to that player.
+//
+// It has to be attached to an avatar-bearing entity: `engine.PlayerEntity` for the local player,
+// the entity of a player in the scene, or an entity with an AvatarShape. On any other entity it
+// is ignored. The client owns the player entities and reuses their ids after players disconnect,
+// so resolve the entity from the user id on every write, and remove the component when the
+// player leaves the scene - a later write to a stale entity lands on whoever holds that id next.
+//
+// The plate does not replace the avatar's name. It is drawn above the nametag as its own line,
+// and it stays visible while the name itself is hidden by AMT_HIDE_NAMETAGS. It does follow the
+// client's nametag visibility setting: a player who turns nametags off sees no plates either.
+// Removing the component, or the entity, removes the plate.
+//
+// The plate is local to the client that renders it and is never relayed to other players. A
+// scene that wants everyone to see the same plate has to distribute it through its own state.
+// Only the scene the local player is currently standing in shows plates; writes from other
+// loaded scenes and from portable experiences are ignored.
