- sink_volume and source_volume knobs now show a dropdown of active
PulseAudio/PipeWire output/input devices (monitors excluded), with
the system-default device marked in the label
- app_volume knob shows a dropdown of running apps (was already a
dropdown, previously had a textarea for group_volume)
- group_volume knob shows a <select multiple> listbox so several apps
can be selected at once with ctrl/shift-click
- Add GET /api/sinks and GET /api/sources backend endpoints
- Add fetchSinks() / fetchSources() in api.ts with AudioDevice type
- Load sinks and sources in App.tsx alongside running apps on refresh
- All 23 frontend tests pass
- FastAPI + uvicorn server (turnup-ui) serving config API and static files
- React + TypeScript frontend: connection, global LEDs, per-knob/button
cards, preset save/load/apply, toast notifications, dark theme
- Vite builds into src/turnup/ui/static/ so no Node.js needed at install time
- PWA assets (manifest, service worker, icon) in ui/public/
- turnup-ui.service systemd user unit; enabled globally via turnupd.install
- PKGBUILD: add python-fastapi + python-uvicorn deps, install UI service file
- pyproject.toml: ui extras group, turnup-ui entry point
