+// Why is this swizzled?
+//   To override the message displayed by `LatestVersionSuggestionLabel`. The built-in version
+//    of this component can only link to another internal version, and the message includes a version
+//     defined in this app. In an archived version of our documentation, neither of those pre-requisites are met.
+//   In the `main` branch of these docs, this component exists in an `archive/` folder, so that it is
+//    ignored by docusaurus. In an archived branch of these docs, the component is moved outside of the `archive/`
+//    folder, so that it is recognized by docusaurus.
+//   This is a very simplified version of the built-in DocVersionBanner file, not intended to support
+//    all use cases. It's only intended to meet the needs of an archived version of the docs.
+// Swizzled from version 2.3.1.
