    /* Carousel Desktop: Show 2 slides? Or keep 1 centered? 
       Prompt says "Desktop: pode mostrar 1 ou 2 por vez". 
       Let's stick to 1 centered for simplicity and focus, or adjust width.
       Let's try to show 2 if width allows, but JS logic needs to handle it.
       For simplicity and robustness with "simple JS", sticking to 1 slide per view is safer 
       unless we implement a more complex track calculation. 
       Let's stick to 1 slide per view but make it wider/nicer.
