//! A micro-framework for associating local CSS snippets with `yew::Component`s
//! in a Custom Element's `ShadowRoot`.
//!
//! Embedding a `<LocalStyle>` element will only create the underlying `<style>`
//! tag once (when `Component::view()` is called the first time), even if
//! multiple copies of the `Component` exist in the tree.
//!
//! # Example
//!
//! ```
//! html! {
//!     <StyleProvider>
//!         <LocalStyle href={ css!("my-style") } />
//!         <h1>{ "I am styled!" }</h1>
//!     </StyleProvider>
//! }
//! ```
