• Always-visible node labels on the local 3D graph (Obsidian-style overlay)
• Expand control opens a floating full-viewport graph panel (Escape / backdrop / collapse to close), with camera reframe so the cluster fills the larger area
• Monochrome smooth spheres, thinner high-contrast links, no type colors or directional arrows
