I’m beginning to think that I’m going to need to add an animation library. But because of the [optimizations](https://elm-lang.org/news/small-assets-without-the-headache) that elm does to reduce asset size, I think my concerns are less relevant - as long as the API for `Alert` remains simple and intiutive.
