 /**

+ * Map Spree PaymentMethod.type (API shorthand) → frontend gateway ID.
+ *
+ * The Store API returns `Spree::Gateway.api_type` — for provider gems
+ * that ship a top-level `Gateway` class, that's the outer module name
+ * stripped of its `Spree` prefix and underscored:
+ *
+ *   SpreeStripe::Gateway          → "stripe"
+ *   SpreeAdyen::Gateway           → "adyen"
+ *   SpreePaypalCheckout::Gateway  → "paypal_checkout"
+ *   SpreeRazorpayCheckout::Gateway → "razorpay_checkout"
+ *
+ * For gems whose shorthand already matches the frontend ID (`stripe`,
+ * `adyen`), the map mostly normalises the suffixed forms. Legacy Rails
+ * STI class names are kept for backwards compatibility with older Spree
+ * backends that haven't been upgraded yet.
+ *
  * Adding a new gateway integration is a single line here.
