ConstA knob is a plain display value in CustomGeoJSONModuleConfig, at the path its id names.
How the module draws is the caller's own MapLibre styling, so visible is the only one. Not knobs:
layers, raw MapLibre layer specs passed through untouched;cluster, MapLibre source options forwarded verbatim and fixed at creation, and
its sourceID, a name;images, image payloads, beforeLayerConfig, a layer placement, and events.
Every custom GeoJSON knob with its kind, description and default. Static data, readable with no map loaded.
