// Populate data/cost-cache.json with real FAA costs via the free HTTP
// configurator endpoint (lib/faa-http.js). No Browserbase, no login.

//   node bin/faa-fetch-http.js --url "<faa product page>" --from-shopify <productId>
//
// For each distinct config on the Shopify product, replays FAA's setter sequence
// and caches the returned cost keyed by configKey. Falls back to the page's
// artworkId when the SKU's artworkId prices null (handles the SKU-vs-listing id
// drift, e.g. Washington Top Hat SKU 65269183 vs live listing 65119339).
