 - Routing bounds enforcement from `SimpleRouteJson.bounds`.
 - Trace width selection from connection width, nominal width, or input defaults.
 - Configurable grid step, clearance, max iterations, via cost, heuristic weight, turn cost, layer costs, layer direction preferences, and track margin.
+- Explicit `SimpleRouteJson.buses` routing, with physical lane ordering, center-out routing, and neighbor-path attraction.
 - Basic post-processing to compact collinear route points and collapse very short same-layer tunnels.
