/**
 * One-time fix: divides price/compare_price/mrp back by the 1.6 INR→NPR
 * factor ImportChandraPharmaProductsCommand applied, so the Chandra Pharma
 * catalog shows the same numbers it did on the old site (chandrapharma.com,
 * priced in INR) instead of the NPR-converted values — per the client's
 * decision to revert to INR display instead of wiring NPR everywhere.
 *
 * Scoped to the "Chandra Pharma" vendor only (matched by slug) — never
 * touches any other vendor's products, even if they also happen to be
 * priced in NPR.
 *
 * Safe to re-run: every reverted product also has its `currency` column
 * flipped from 'NPR' to 'INR' as it goes, and the query only ever selects
 * products still marked 'NPR' — so a second run finds nothing left to do
 * instead of halving prices again.
 *
 * Usage:
 *   php artisan chandra-products:revert-to-inr
 *   php artisan chandra-products:revert-to-inr --dry-run
 *
 * After running, set Admin → General Settings → Currency to
 * "INR — Indian Rupee" and Save — the storefront/admin price prefix now
 * reads that setting (see app/helpers.php's currency_symbol()/format_price()).
