// TK-11333 — UNDO for create-trade-segment.mjs.
// Deletes the `DW Trade / Designers` segment we created, and recreates the broken
// `interior-designer-res` segment from the recorded snapshot (so state returns exactly).
// DRY-RUN BY DEFAULT; --apply to write.
//
// WARNING: if any free-ship CODE still references the segment (create-freeship-codes.mjs),
// delete the codes FIRST (create-freeship-codes-undo.mjs) — this script will warn and refuse
// to delete a segment that is still in use.
