One fetched file drives two rendered layers at once: a density surface low in the stack and a labelled marker layer above it.

• CustomGeoJSONModule.create takes a named source per dataset, and show with no source name feeds the one fetched collection to both.
• images registers the canvas icon with the module rather than the style, so it survives a base map style change on its own.
• events.markers scopes clicks and hovers to the marker source alone, leaving the density surface inert.
• attribution.credits credits the dataset next to TomTom, and the credit stays through every style switch.
