This host deliberately carries no tag.
Payment is not part of this version of the demo. Nothing on this page loads a container, sets a cookie or reads one, because the provider's payment page never would.
What the payment step would add
A Stripe Checkout session in test mode that carries the journey id as a client reference, and a webhook that confirms the purchase and attaches it to the journey, even if the visitor never comes back from the payment page.
NOT IN THIS VERSION
For now this page is a link target and nothing more.
