Restoring catalog fields to the values captured in a snapshot.
A rollback replays a snapshot in reverse: for each recorded field, write the old value back — unless a subsequent manual edit changed it, in which case a good rollback engine detects the drift and asks before overwriting. Shopify has no native rollback for product edits; the native editor and CSV import both commit destructively. Snapshot-based rollback is the single feature that turns a bad Friday-night edit into a five-second correction.
