 If you're new to custom elements, often referred to as "web components," this section will familiarize you with how to use them.
 
+## Awaiting Registration
+
+Unlike traditional frameworks, custom elements don't have a centralized initialization phase. This means you need to verify that a custom element has been properly registered before attempting to interact with its properties or methods.
+
+You can use the [`customElements.whenDefined()`](https://developer.mozilla.org/en-US/docs/Web/API/CustomElementRegistry/whenDefined) method to ensure a specific component is ready:
+
+```ts
+await customElements.whenDefined('wa-button');
+
+// <wa-button> is ready to use!
+const button = document.querySelector('wa-button');
+```
+
+When working with multiple components, checking each one individually can become tedious. For convenience, Web Awesome provides the `allDefined()` function which automatically detects and waits for all Web Awesome components in the DOM to be initialized before resolving.
+
+```ts
+import { allDefined } from '/dist/webawesome.js';
+
+// Waits for all Web Awesome components in the DOM to be registered
+await allDefined();
+
+// All Web Awesome components on the page are ready!
+```
+
 ## Attributes & Properties
 
 Many components have properties that can be set using attributes. For example, buttons accept a `size` attribute that maps to the `size` property which dictates the button's size.

+title: Reduce FOUCE
+description: Utility to improve the loading experience by hiding non-prerendered custom elements until they are registered.
+file: styles/utilities/fouce.css
+icon: spinner
+---
+
+While convenient, autoloading can lead to a [Flash of Undefined Custom Elements](https://www.abeautifulsite.net/posts/flash-of-undefined-custom-elements/).
+The [FOUCE style utility](/docs/utilities/fouce/#opting-in) (which is automatically applied if you use the [Web Awesome utilities](/docs/utilities/)) takes care of hiding custom elements until they and their contents have been registered, up to a maximum of two seconds.
+
+In many cases, this is not enough, and you may wish to hide a broader wrapper element or even the entire page until all WA elements within it have loaded. To do that, you can add the `wa-reduce-fouce` class to any element on the page or even apply it to the whole page by placing the class on the `<html>` element.
+
+```html
+<html class="wa-cloak">
+  ...
+</html>
+```
+
+As soon as all elements are registered _or_ after two seconds have elapsed, the autoloader will show the page. The two-second timeout prevents blank screens from persisting on slow networks and pages that have errors.
+
+:::details Are you using Turbo in your app?
+
+If you're using [Turbo](https://turbo.hotwired.dev/) to serve a multi-page application (MPA) as a single page application (SPA), you might notice FOUCE when navigating from page to page. This is because Turbo renders the new page's content before the autoloader has a change to register new components.
+
+The following function acts as a middleware to ensure components are registered _before_ the page shows, eliminating FOUCE for page-to-page navigation with Turbo.
+
+```js
+import { preventTurboFouce } from '/dist/webawesome.js';
+
+preventTurboFouce();
+```

-## How does it work?
-
-The utility consists of a timeout (`2s` by default) and a fade duration (`200ms` by default).
-- If the element is _ready_ before the timeout, it will appear immediately.
-- If it takes longer than _timeout_ + _fade_, it will fade in over the fade duration.
-- If it takes somewhere between _timeout_ and _timeout_ + _fade_, you will get an interrupted fade.
-
-An element is considered ready when both of these are true:
-1. Either It has been registered or has a `did-ssr` attribute (indicating it was pre-rendered)
-2. If it’s a Web Awesome component, its contents are also ready
-
-## Customization
-
-You can use the following CSS variables to customize the behavior:
-
-| Variable | Description | Default |
-| --- | --- | --- |
-| `--wa-fouce-fade` | The transition duration for the fade effect. | `200ms` |
-| `--wa-fouce-timeout` | The timeout after which elements will appear even if not registered | `2s` |
-
-The fade duration cannot be longer than the timeout.
-This means that you can disable FOUCE reduction on an element by setting `--wa-fouce-timeout: 0s`.
-
-For example, if instead of `did-ssr` you used an `ssr` attribute to mark elements that were pre-rendered, you can do this to get them to appear immediately:
-
-```css
-[ssr] {
-  --wa-fouce-timeout: 0s;
-}
-```
-
-You can also opt-out from FOUCE reduction for an element and its contents by adding the `.wa-fouce-off` class to it.
-Applying this class to the root element will disable the utility for the entire page.
