CARTO's raster basemaps — leaflet's CartoDB.* providers and the first two
of mapview's default basemaps — draw an "API KEY REQUIRED" watermark on
every tile since Sep 2026. This attaches cc_vector_basemap_deps() to a
Leaflet or mapview map, so each CARTO raster layer on the page is drawn
instead from the same basemap's vector GL style (cc_basemap_style()).
Provider names, layer groups and the layer control are unchanged; other
tile layers (Esri, OpenStreetMap) pass through.
