Change the [View Transition built-in animation](https://docs.astro.build/en/guides/view-transitions/#built-in-animation-directives) options.
The `transition:animate` value `morph` has been renamed to `initial`. Also, this is no longer the default animation.
If no `transition:animate` directive is specified, your animations will now default to `fade`.
Astro also supports a new `transition:animate` value, `none`. This value can be used on a page's `<html>` element to disable animated full-page transitions on an entire page.
