How this pair works
Your Fountain file is parsed into a canonical screenplay model (by verified content, not just the file extension), then rendered as Celtx. Celtx background: Celtx (2001) was the free pre-production suite many writers started on; the desktop app was discontinued in 2013 in favor of cloud subscriptions, and in 2022 the cloud itself stopped creating legacy file types — orphaning local .celtx files for good.
