I'll update the design with a dark theme inspired by the modern aesthetics shown, and fix the spinning logic so wheels spin for different durations.

I've made significant improvements:

1. Different spin durations: The name wheel spins for 3.5-4.5 seconds while the number wheel spins for 4.5-6 seconds, so they finish at noticeably different times.
2. Different spin speeds: Each wheel has its own base rotation count - names spin 6-8 full rotations, numbers spin 4-6 rotations, so they move at visibly different speeds.
3. Modern dark theme: Updated to a sleek dark color scheme with subtle purple-blue undertones, vibrant accent colors (green for names, amber for numbers), and improved contrast.
4. Polished visuals: The wheels now have subtle shadows, a glow effect when spinning, refined center circles with gradients, and better typography with tracking and spacing. The UI has rounded corners, proper spacing, and a clean card-based layout.

Now let me fix the wheel component for sharper text and a friendlier look with highlighting:

Now let me update the page to pass the highlighted items to the wheels:

I've made all the updates:

1. Italian subtitle: Added "Abbina nomi a numeri di porta casualmente" below the English subtitle in a smaller, italic style.
2. Sharper text on wheels: Used devicePixelRatio scaling on the canvas to render at 2x (or higher) resolution, eliminating blurriness on retina displays.
3. Friendlier/fuller wheels: Added radial gradients to each slice (lighter in center, darker at edges), a decorative outer ring, thicker white borders between slices, and a more polished center hub with an inner dot.
4. Longer spin times: Names now spin 5-6.5 seconds (8-11 rotations), numbers spin 6.5-8.5 seconds (5-8 rotations) - noticeably different durations.
5. Highlighted results: When a result is shown, the winning slice on each wheel gets a bright white glow/highlight effect so you can clearly see which segment landed.
