"""horizon-dock — a hover-scrollable orbital dock for hyprdrive, matching
orbit-menu's visual language.
Single-instance, same pattern as astal-menu/orbit-menu's main.py: the first
launch builds the (hidden) window and holds; later invocations forward their
verb over D-Bus via scripts/horizon-dock.sh instead of spawning a second
python3+GTK4 process.
main.py run the resident instance (stays hidden until toggled)
main.py --show slide/fade in
main.py --hide slide/fade out
main.py --toggle whichever of the above applies
