Restore Biome

Puts a region back the way a paint snapshot recorded it.

Fields

Field	Type	Description
`snapshotId`	`String`	Snapshot name recorded by a paint action
`consume`	`Boolean`	Delete the snapshot once restored

Restoration runs off the main thread and is grouped by biome, so a large region is put back in a few scheduled passes rather than one write per cell.

If the snapshot does not exist, or refers to a world that is no longer loaded, the action logs it and does nothing — it never guesses at a fallback.

Leave consume off when a zone is painted and restored repeatedly; turn it on for a one-shot event so the file does not linger.
