I'm using Harlowe in the newest version of web Twine. I want to be able to prevent certain passages from being added to the published HTML file; not just inaccessible but truly absent from the file. I've heard that this can be done with passage tags, and I've tried Twine.private but it doesn't seem to work. Is there any other way to do this other than making a copy and deleting all unwanted passages before publishing that file? Thank you in advance.
