CMS UI with View mode
The current CMS admin allows for listing articles and on click will open article edit form.
<ContentHeader (?) with buttons: "Edit" and "View". "Edit" is the current UI and clicking "View" should render the article as it is rendered to the end user on the frontend.
"View" mode should not try to "preview" what is in the HTML editor, it should display the saved article version.
No need to make this SSR compliant.
