unom Flatpak repository

Install the Punktfunk Linux client (auto-adds Flathub for the GNOME runtime, then tracks updates):

flatpak install --user https://flatpak.unom.io/io.unom.Punktfunk.flatpakref
flatpak run io.unom.Punktfunk

Or add the whole remote: flatpak remote-add --user --if-not-exists unom https://flatpak.unom.io/unom.flatpakrepo
