- Mute button click no longer triggers node drag (priority check in onMouseDown)
- Volume slider clamped to 0-100% in both display and API
- Added draggable circle handle on slider end
- Volume drag state tracked globally, not per-element
- Backend: fixed spa_pod_builder API usage (push_object/pop with frame)
- Volume calculated from SVG coordinates properly via svgPoint conversion
- Volume slider on every node (green bar, draggable)
- Mute toggle button (M/m) on every node
- Backend: read volume/mute from PipeWire node props
- Backend: POST /api/volume {node_id, volume} to set volume
- Backend: POST /api/mute {node_id, mute} to toggle mute
- Graph JSON includes volume and mute fields per node
- Slider supports drag-to-adjust with mouse
