== Background
We need to notify our community that PDFs for books will be unavailable for the short-term directly on the books page. We may do this by either:
- changing the text on the current banner and keeping the banner the same
- visually highlighting the severity of the issue on the banner
== Acceptance Criteria
[] Update current special:book banner with the new banner
[] Replace banner on saved book pages (currently, there is a banner that forward to a secondary latex option for books):
- example user namespace: https://en.wikipedia.org/wiki/User:OVasileva_(WMF)/Books/Trial_Book_1
- example book namespace: https://en.wikipedia.org/wiki/Book:13th_Floor_Elevators
[] Update MW page with banner text
[] Remove OCG as an option from the book creator
