Everything seems ready for the actual mass #Python 3.14 rebuild in #Fedora Rawhide. We'll meet with @karo and @frenzy early next week to fire off and babysit the builds.

@hroncok @frenzy aaaand merged! ๐ŸŽ† Maintainers can stop holding the breath and build in Rawhide again.
Doing this during the #FlockToFedora conference and with Miro's indisposition has certainly been a new level of the challenge.
@karo @hroncok @frenzy your work is very much appreciated ๐Ÿ™๐Ÿผ๐Ÿ™‡๐Ÿป
