//! The backend a build without a portal installs.
//!
//! It is a real implementation, not a stub. Every request is refused on the
//! spot with [`Refusal::NoPortal`], so a game that asks for an ad gets an
//! answer on that frame instead of waiting for a host that is not there, and
//! [`NoPortal::status`] says the same thing before anything is asked at all:
//! `hosted: false` and every feature `Unavailable(NoPortal)`. A game can hide
//! its rewarded button, its cloud banner and its "watch to revive" offer from
//! that, and everything it does ask is a warning in a log rather than silence.
