Every role carried a single representative type, so setting "Images" changed image/png and left image/jpeg wherever it landed. That is how this desktop ended up opening PDFs in GIMP, PNGs in a pixel-art editor and MP3s in a video transcoder: nobody chose any of it, applications registered themselves for everything they could read, and the roles governed one type each. Roles now own families and write every type when set, the settings page exposes the documents, text and archives roles it never offered, and a new seed command curates a fresh machine during setup while always keeping a choice the user has already made. The shipped editor entry launches kitty explicitly. The stock nvim.desktop sets Terminal=true, which defers to whatever the system considers default rather than the terminal this desktop themes.
