//! Badge component for status indicators
//!
//! Displays a small badge with text, useful for counts, status, or labels.
//!
//! # Example
//!
//! ```rust,ignore
//! use rnk::prelude::*;
//! use rnk::components::Badge;
//!
//! fn app() -> Element {
//!     Box::new()
//!         .flex_direction(FlexDirection::Row)
//!         .gap(1.0)
//!         .children(vec![
//!             Badge::new("3").variant(BadgeVariant::Primary).into_element(),
//!             Badge::new("New").variant(BadgeVariant::Success).into_element(),
//!             Badge::new("Error").variant(BadgeVariant::Error).into_element(),
//!         ])
//!         .into_element()
//! }
