it literally just needs a file called .nojekyll in the root of the repository (the file can be empty 😃 )

hmmm - this looks like some kind of permissions error for the browser, as opposed to something related to the outputs of Jupyter Book (403 forbidden is a permissions thing)…I also see the word “IFrame” on the page so it may be related to that
