bevy_ios_toolkit 0.3.2

//! Desktop walkthrough of the ad flow against the built-in fake backend.
//!
//! ```text
//! cargo run --example ads
//! BEVY_ADMOB_FAKE_NO_FILL=interstitial cargo run --example ads   # interstitial won't fill
//! BEVY_ADMOB_FAKE_REWARD_AMOUNT=50 cargo run --example ads        # bigger reward
//! BEVY_ADMOB_FAKE_CONSENT=required cargo run --example ads        # consent form path
//! ```
//!
//! It shows a banner, preloads + shows an interstitial and a rewarded ad,
//! prints every outcome, then exits.
