bevy_ios_toolkit 0.3.0

//! Desktop walkthrough of the store flow against the built-in fake backend.
//!
//! ```text
//! cargo run --example store
//! BEVY_IOS_FAKE_OWNED=com.example.removeads cargo run --example store
//! BEVY_IOS_FAKE_CANCEL=1 cargo run --example store
//! ```
//!
//! It loads two products, buys one, prints the outcome + entitlements, exits.
