//! Single AnimatedIcon component using registry pattern

//! This module provides a unified AnimatedIcon component that replaces individual
//! animated icon components with a single registry-based implementation.

/// Single AnimatedIcon component using registry lookup
///
/// This component replaces all individual animated icon components with a unified
/// registry-based implementation for better build performance while supporting CSS animations.
///
/// # Example
/// ```rust
/// use icons::leptos_animated::{AnimatedIcon, AnimatedIconType};
/// use leptos::prelude::*;
///
/// fn example() -> impl IntoView {
///     view! {
///         <AnimatedIcon icon=AnimatedIconType::Heart class="w-6 h-6" />
///         <AnimatedIcon icon=AnimatedIconType::Plus class="text-blue-500" />
///     }
/// }
/// ```
