    Type Alias AreaAnalyticsBeforeLayerConfig

    Per-layer-type positioning configuration for area analytics layers.

    Controls where each analytics layer type sits in the map's layer stack independently. Each property accepts 'top' (above all layers) or a well-known style layer ID. Omitted properties fall back to their default positions.

    // Move all layers below the lowest label
    const config: TrafficAreaAnalyticsConfig = {
      beforeLayerConfig: {
        heatmap: 'lowestLabel',
        hexgrid: { flat2D: 'lowestLabel', extrusion3D: 'lowestPlaceLabel' },
        square:  { flat2D: 'lowestLabel', extrusion3D: 'lowestPlaceLabel' },
      },
    };

    // Only reposition the heatmap layer
    const config: TrafficAreaAnalyticsConfig = {
      beforeLayerConfig: { heatmap: 'top' },
    };
    type AreaAnalyticsBeforeLayerConfig = {
        heatmap?: BeforeLayerConfig;
        hexgrid?: { extrusion3D?: BeforeLayerConfig; flat2D?: BeforeLayerConfig };
        square?: { extrusion3D?: BeforeLayerConfig; flat2D?: BeforeLayerConfig };
    }
