// TK-11333 — remove the blunt "Free Shipping (No Tracking)" $0–$45 band so base shipping =
// honest ups/fedex carrier rates (fixes GAP2: free untracked shipping leaking to ANY product
// <= $45). Free SAMPLE shipping now comes from the segment/all-customer CODES instead.
//
// MECHANISM: the delivery API has NO methodDefinitionsToDelete, but a method has an `active`
// flag — so we DEACTIVATE the free method (exact-GID, trivially reversible) rather than delete.
// LAST STEP — run only AFTER grandfather + proto-autoapply PASS + codes exist.
//
// GATED (customer-facing shipping change). DRY-RUN BY DEFAULT; --apply to write.
// Snapshots to verification/remove-band-snapshot.json; undo = restore-band.mjs (reactivates
// + restores the exact prior conditions from that snapshot).
