Arena: area-of-interest culling
A 2400x1600 world with ~150 server-driven NPCs, but your client only
receives what is inside a 420-unit radius around you - live.smooth({ interest }) culls the rest per
subscriber, with LOD bands throttling the fringe. Move with WASD or
arrow keys; your dot is predicted through the shared apply, so it responds on the same frame.

live coasting stale
Fringe entities (beyond 300 units) update every 6th tick, the mid ring every 3rd - watch dots dim as they coast between updates. Walk toward a quiet corner and the receiving count drops; the world does not.
