A hierarchical dependency graph rendered as a spiral software galaxy: a central `main` node fans into arms that branch and spiral outward, each node seeded on a radial layout (radius by depth, angle by arm plus depth twist) and kept alive by a gentle GPU force pass that springs to its parent and eases back toward its seeded slot. Colour encodes depth from a bright core to a deep-purple rim; the camera slowly orbits and the mouse steers it, while pointerDown lights up one whole spiral arm.
