The jump-link graph linked the whole catalogue: 3.7 million links at 8 pc, 7.4-7.8 s in the
worker and a 443-515 ms frame on the main thread when they landed, and most of them between stars
that were neither drawn nor clickable. A graph request now carries the star field's drawn stars,
and the worker links only those, over an index of its own with cells as wide as the range. The
scene asks again once a new drawn set has held still for 250 ms.
The renderer is handed the graph's bounding sphere instead of computing it: three.js walked every
vertex on the main thread in the first frame that drew a new graph, 48-55 ms at 8 pc.
