Rotterdam, Amsterdam and Utrecht go in as names, and the route through them comes back with green waypoint pins outlined in translucent orange.

• RoutingModule.create takes waypoints.icon.style up front, so fillColor, outlineColor and outlineOpacity stand in for hand-built markers.
• bboxFromGeoJSON frames the map on the stops before the route exists, so nothing needs fitting afterwards.
• showWaypoints and showRoutes take the stops and the calculateRoute response as they come, with no layer wiring.
