 Why Lazy Loading Matters in Livewire v3
---------------------------------------

Every Livewire component that renders on the initial request adds to your server's time-to-first-byte. For dashboards with heavy aggregations, charts, or permission-gated widgets, that cost compounds fast. Livewire v3 ships three complementary tools: **lazy components**, **deferred updates**, and the emerging **islands** mental model. Used together they let you serve a shell instantly and hydrate expensive pieces asynchronously.

Lazy Components: The Basics Done Right
--------------------------------------

Adding `#[Lazy]` to a component tells Livewire to render a placeholder on the first request and fire a subsequent network call to hydrate the real component.
