Function progress_container 

pub fn progress_container() -> MultiProgress

The indicatif::MultiProgress a multi-bar command (bundle pull) draws its bars into: the process-global one when a subscriber is installed — so its bars share stderr with log lines through indicatif::MultiProgress::suspend — or a fresh standalone container on the default silent path, where there are no log lines to coordinate with. Either way the bars stack coherently, and a non-terminal stderr auto-hides them.
