// TK-11333 — UNDO for remove-band.mjs (and general "put the free band back"). Snapshot-driven
// TRUE inverse with two paths:
//   • method PRESENT (was deactivated) -> reactivate + restore exact prior conditions.
//   • method ABSENT (was deleted, or never present) -> RECREATE it from the snapshot
//     (DeliveryRateDefinition $0 + the snapshot's price conditions) in the Domestic zone.
// Snapshot source: verification/remove-band-snapshot.json, else raise-band-snapshot.json.
// DRY-RUN BY DEFAULT; --apply to write.
