Essentially a desktop environment that uses Gnome's compositor and is made to look like Gnome. This is where Libadwaita stems from before being adopted as an official project.
Since libadwaita was officially added into GNOME, there's been an attempt to make GNOME more mobile friendly, making PHOSH redundant however there's still a few projects using it by default due to it's history in the Linux mobile relm.
