    function setCase(textTransform) {
        if (!map.isStyleLoaded()) return;
        const layers = map.getStyle().layers;
        for (const layer of layers) {
            if (layer.type === 'symbol' && layer.layout && layer.layout['text-field']) {
                map.setLayoutProperty(layer.id, 'text-transform', textTransform === 'none' ? undefined : textTransform);
