1//! Mobiler runtime — the developer-facing API.
2//!
3//! Implement [`MobilerApp`] with your **typed** events, model, and view (built
4//! from the [builders](#functions)). Mobiler wraps it in [`MobilerShell`], a
5//! Crux app speaking the fixed UI ABI ([`mobiler_ui`]); you never touch the wire
6//! protocol. Device APIs are capabilities via [`Cx`].

455/// and shows a back affordance (top-bar arrow + system back button) firing
456/// `on_back` whenever the stack can pop.
