slotName

Determines the position of the route layers in the map style. Adding a slot to the style can be done at runtime with code like:

style.addPersistentLayer(slotLayer("runtimeSlotId") {
  slot("middle")
})

The slot layer needs to be added persistently, because so are the route line layers, and they require the slot reference immediately on style reload to be correctly recreated.
