 Why Initial Page Weight Kills Perceived Performance
---------------------------------------------------

Every Livewire component mounted on a page adds a JSON snapshot to the initial HTML payload. For dashboards with a dozen widgets, that snapshot cost compounds quickly. Livewire v3 ships three complementary tools to defer that cost: **lazy components**, **islands**, and the `wire:init` / `#[Lazy]` deferred-loading pattern. They are not interchangeable — knowing which to reach for is the real skill.

---

Lazy Components with `#[Lazy]`
------------------------------

Adding the `#[Lazy]` attribute to a component class tells Livewire to skip the full mount during the initial render and instead emit a lightweight placeholder. A subsequent HTTP request hydrates the real component.
