// Fixture-fed harness for the three sound services that shell out:
// SoundCards (pactl list cards / set-card-profile), SoundRouting (pactl
// move-sink-input) and SoundDefaults (pw-metadata -n default).
//
// Nothing here touches the real audio graph. The contracts that drive this file
// replace pactl and pw-metadata with recording stubs, so what is under test is
// the parsing and the argv -- not PipeWire, which has its own opinions and a
// different set on every machine.
//
// Application groups arrive as plain objects with the same shape AudioStreams.js
// produces, because that is what the services are handed at runtime and it is
// the part a refactor is most likely to break silently.
