flatpak build-finish rejects it outright ("Unknown socket type
pipewire, valid types are: x11, wayland, pulseaudio, session-bus,
system-bus, fallback-x11, ssh-auth, pcsc, cups, gpg-agent,
inherit-wayland-socket"). Direct PipeWire socket access is granted via
--filesystem=xdg-run/pipewire-0 instead (same approach other
sandboxed apps needing raw PipeWire, e.g. OBS Studio's flatpak, use).
