The parts, named after the module's event scopes, and where each sits by default:
places — the markers and their labels, selected places, clusters with their badges and
counts, and entry points. Above the map's layers, except the small POI dots the base-map and
pin-clustered marker types draw, which sit below the map's place labels. A target puts them
all beneath it, the dots right under the markers.connections — the lines PlacesModule.showConnections draws, and their labels. Below
the map's labels.Each part keeps its own layers' order wherever it goes. A target the style lacks puts the part on top.
Where the places module's layers sit in the map's layer stack: one target for everything it draws, or one per part of it.
