// READ-ONLY Printful catalog helper for /wear go-live wiring (TK-10286).
//
// Once PRINTFUL_API_KEY is set, this fetches a Printful catalog product's variants
// and prints a suggested `variants` map ({ "color/size": variant_id }) to paste into
// data/wear-templates.json for each garment. It ONLY issues GET requests to the
// Printful catalog — it never creates, confirms, or touches an order. Safe to run
// any time the key is present; a no-op (prints guidance) when it is not.
//
// Usage:
//   node scripts/fetch-printful-catalog.mjs                 # list candidate products
//   node scripts/fetch-printful-catalog.mjs <productId>     # dump variants for a product
