// TK-11333 — CORRECT band-retune executor. Targets the LIVE free-sample band on the
// DEDICATED "Samples — Free Shipping (No Tracking)" profile (96764067891), method
// 730269646899, Domestic(US) zone 367888826419 — NOT the General profile.
//
// WHY THIS EXISTS: remove-band.mjs and raise-band.mjs both hardcode the GENERAL profile
// (29033627699), which no longer carries the band. That mis-targeting is what produced the
// false "band already gone / remove is a no-op" claim. This script reads + (gated) edits the
// REAL band. Per the DTD Option-A verdict the recommended action is NO CHANGE ($45 already
// gives ~10 samples free, comfortably covering retail 5+5); --cap is only for an optional
// tighten (e.g. 42.50 = exactly 10) IF Steve wants it.
//
//   node retune-samples-band.mjs                 # READ-ONLY: print the live band + recommend
//   node retune-samples-band.mjs --cap 42.50 --apply   # GATED write: set the <= cap to 42.50
//
// Undo: verification/samples-band-retune-snapshot.json records the pre-change conditions;
// re-run with --cap <old-value> --apply to restore.
