"""audio-panel — PipeWire mixer panel for hyprlua. Five tabs:
|
|
Applications / Input Devices / Output Devices / Cards / General Settings,
|
|
each a horizontally-scrolling row of cards (see window.py, ui/*_tab.py).
|
|
|
|
Single-instance, same pattern as astro-menu/horizon-dock/transmitter-panel's
|
|
main.py: the first launch builds the (hidden) window and holds; later
|
|
invocations forward their verb over D-Bus via scripts/audio-panel.sh
|
|
instead of spawning a second python3+GTK4 process.
|
|
|
|
main.py run the resident instance (stays hidden until toggled)
|
|
main.py --show show
|
|
main.py --hide hide
|
|
main.py --toggle whichever of the above applies
