//! Divider component for visual separation
//!
//! Creates horizontal or vertical dividers with optional labels.
//!
//! # Example
//!
//! ```rust,ignore
//! use rnk::prelude::*;
//! use rnk::components::Divider;
//!
//! fn app() -> Element {
//!     Box::new()
//!         .flex_direction(FlexDirection::Column)
//!         .children(vec![
//!             Text::new("Section 1").into_element(),
//!             Divider::horizontal().into_element(),
//!             Text::new("Section 2").into_element(),
//!             Divider::horizontal().label("OR").into_element(),
//!             Text::new("Section 3").into_element(),
//!         ])
//!         .into_element()
