  ## Example Usage

  Here is a basic example of setting up a badge component:

  ```elixir
  <Badge.root>
    Default Badge
  </Badge.root>
  ```

  You can customize the badge with different variants and HTML elements:

  ```elixir
  <Badge.root variant="secondary" as="div" class="extra-class">
    Secondary Badge
  </Badge.root>
  ```

  ## Attributes

  - `:variant` - The style variant of the badge. Available options:
    - `:default` (default)
    - `:secondary`
    - `:destructive`
    - `:outline`
  - `:as` - The HTML element to use for the badge. Default is `"span"`, can be `"div"`.
  - `:class` - Additional CSS classes to apply to the badge.
  - `:rest` - Any additional attributes to apply to the badge's root element.

  ## Slots

  - `:inner_block` - The content to be displayed inside the badge.
