"""Cards tab: horizontally-scrolling row of every sound card (pactl cards) —
onboard audio, USB headsets, HDMI, Bluetooth devices — each with just its
profile dropdown (pro-audio vs stereo duplex etc.). See ui/profile_card.py
for why this is its own tab rather than living on individual device cards."""
