These options may mean something special depending on the type of input, otherwise they are emitted as HTML attributes. See the [Rails documentation](https://guides.rubyonrails.org/form_helpers.html) for more information. In addition, the usual Primer utility arguments are accepted in system arguments. For example, passing `mt: 2` will add the `mt-2` class to the input. See the Primer system arguments docs for details.
