Documentation
The Avatar components display a user's profile picture or fallback initials. Use the composable `Avatar`, `AvatarImage`, and `AvatarFallback` primitives when you need full control, or `ImageAvatar` for the common image-with-fallback case.

## Component Structure

```rust
Avatar {
    aria_label: "Jane Doe",
    AvatarImage {
        src: "https://example.com/avatar.png",
        alt: "Jane Doe",
    }
    AvatarFallback { "JD" }
}
```

```rust
ImageAvatar {
    src: "https://example.com/avatar.png",
    alt: "Jane Doe",
    on_state_change: |state: AvatarState| { /* image is loading/loaded/failed */ },
    "JD"
}
```
