+ * TK-10029 ROLLBACK: reverse the Roll->"Mural (per m²)" relabel using a durable
+ * pre-apply rollback ledger. For each recorded rename, renames the canonical option
+ * value BACK to its captured old_value. Dry-run by default; --apply to execute.
+ *
+ * Usage:
+ *   node scripts/rollback-relabel.js --ledger data/relabel-rollback-map-<ISO>.json
+ *   node scripts/rollback-relabel.js --ledger <file> --apply
