How this node works
When the panel is parked, a lever pushes a hidden bar — the drop-seal or «guillotine» — down onto the floor, closing the gap that movement needs. It is the make-or-break of the acoustic performance: the panel can be heavy, but if the bottom edge does not seal, the sound passes straight under it.
