-//! # OSUI
+use std::sync::Arc;
-//!
-//! A terminal user interface (TUI) library providing customizable components
-//! to build command-line interfaces in Rust. OSUI enables users to create
-//! interactive CLI applications with various UI elements and handle keyboard
-//! input for real-time events.
-//!
-//! ## Example Usage
-//!
-//! ```rust
-//! use osui::prelude::*;
-//!
-//! #[component]
-//! pub fn App() -> Element {
-//!     let count = State::new(0);
-//!
-//!     rsx! {
-//!         button {
-//!             class: "btn",
-//!
-//!             on_click: fn(_, _, _) @count {
-//!                 count += 1;
-//!             },
-//!
-//!             "The current count is: {count}"
-//!         }
-//!     }
-//! }
-//! fn main() {
-//!     launch!(App);
-//! }
-//! ```
-//!
-//! ## Modules
-//! - `ui` - Contains all user interface components, enabling rich CLI experiences.
-//! - `utils` - Utility functions for common TUI tasks such as clearing the screen.
