// Delegate for in-browser Fast Checkout (FC) surface display.
// Currently FC surface is eligible only for a particular set of domains on
// click on an empty focusable field during checkout flows.
//
// If the surface was shown once, it won't be triggered again on the same page.
//
// It is supposed to be owned by the given |BrowserAutofillManager|, and
// interact with it and its |FastCheckoutClient|.
//
// Due to asynchronous parsing, showing the FC surface proceeds in two stages:
// IntendsToShowFastCheckout() is called before parsing, and only if this
// returns true, TryToShowFastCheckout() is called after parsing. This is
// necessary for the keyboard suppression mechanism to work; see
// `TouchToFillKeyboardSuppressor` for details.
