       Why Islands Matter in Livewire v3
---------------------------------

A common mistake is treating every Livewire component as equally urgent. A dashboard with a stats summary, a data table, and a notification feed does not need all three hydrated before the browser paints. Livewire v3's lazy loading system lets you declare exactly which components are deferred, what placeholder they show while loading, and whether they should load immediately after paint or only when they scroll into view.

This is the island architecture idea applied to Livewire: each component is a self-contained unit of interactivity that hydrates independently.

The `lazy` Attribute
--------------------

The simplest form is the `lazy` attribute on a component tag:

```blade

```

Livewire renders the component's `placeholder()` method on the server during the initial request, then fires a subsequent network request to fully hydrate the component after the page loads. No JavaScript configuration required.

### Providing a Meaningful Placeholder

Without a placeholder, users see nothing until hydration completes. Override `placeholder()` in the component class:

```php
public function placeholder(): string
{
    return
