//! Hello World via the iced backend.
//!
//! Demonstrates the iced UiCtx adapter with COOLJAPAN theming.
//!
//! Run with:
//! ```sh
//! cargo run --example hello_iced --features iced -p oxiui
//! ```
//!
//! # Architecture note
//!
//! This example uses iced directly (not through the `App` facade) because
//! iced is retained-mode while the facade's content-closure API is
//! immediate-mode. M3 will wire the full closure → message round-trip through
//! the facade. At M2 this example is the canonical iced demo.
