Payment-only iframe embed. Renders just the Gr4vy provider iframe
(no address / shipping / cart UI). Email is collected by the Gr4vy
iframe in proxy-mode sessions. Used when the merchant has built
their own checkout UI and only needs Throttle to handle payment
authorization + capture.
parentOrigin must match an entry in the merchant's allow-list.
The iframe auto-resizes on throttle.resize events.
