/* Rollback for the TK-11248 batch. Reverses whichever step was applied.
 *   --step=11238  restores Aries title from TK-11238-restore.json
 *   --step=10405  recreates the 12 deleted Default-Title variants from TK-10405-restore-map.json
 *                 (Shopify assigns NEW variant ids; SKU/price/options restored)
 * DRY-RUN by default; --apply to fire. Rollback is the undo of a recorded write,
 * so it only needs --apply (no sentinel) — but it prints exactly what it will do first.
 *
 * Usage:
 *   node rollback-TK11248.js --step=11238            # dry-run
 *   node rollback-TK11248.js --step=11238 --apply    # restore title
 *   node rollback-TK11248.js --step=10405 --apply    # recreate 12 variants
