+ * provider's async callback/webhook, anything else) behind one uniform
+ * moment: "payment is confirmed, place the order."
+ *
+ * confirm() is the only thing a driver is required to do: once it has,
+ * by whatever mechanism is native to that gateway, independently decided
+ * the payment succeeded, it calls Modules\Core\Checkout\Services\
+ * CheckoutService::placeOrder($fingerprint) itself — no driver ever calls
+ * Lunar\Models\Cart::createOrder() directly. This is what lets the
+ * storefront checkout sequence stay uniform regardless of which provider is
+ * active: set addresses, select shipping, hand off to whichever driver is
+ * configured, and the driver decides when (or whether) the order actually
+ * gets created. See docs/checkout.md / docs/payments.md.
