In order to better match the [EP Binding](https://ucp.dev/latest/specification/embedded-checkout/) of UCP we are renaming the web events to match 1-1. This means `checkout:*` becomes `ec.*` in event names

There was a problem hiding this comment.
Glad we're doing this!
What do you think about encouraging an an enum for the events rather than a string, to align more with the other platforms?
checkout.addEventListener(CheckoutProtocol.start, (event) => {})
checkout.addEventListener(CheckoutProtocol.close, (event) => {})
checkout.addEventListener(CheckoutProtocol.totalsChange, (event) => {})
