Adds complete vector basemaps beneath existing operational layers. Theme
changes never replace the map style, sources, filters, feature state, camera
or popups owned by the host. Only the active basemap is downloaded initially.
Call activate after the host's local initial style has loaded. Glyph URLs
must agree with an existing host glyph template: overwriting it would change
operational labels. Custom styles can use the same template or omit glyphs.
