//! use crate::prelude::*;
//!
//! rsx! {
//!     Layout {
//!         header: rsx! {
//!             Header {
//!                 h1 { "My App" }
//!             }
//!         },
//!         aside: rsx! {
//!             Aside {
//!                 nav {
//!                     a { "Link 1" }
//!                     a { "Link 2" }
//!                 }
//!             }
//!         },
//!         footer: rsx! {

//!                 "© 2026 Hikari UI"
//!             }
//!         },
//!         h1 { "Main content" }
