What the model said
Done. Here's what I improved: 1. **Visibility** — added white fill to the circle (it was invisible before) 2. **Responsive design** — changed `100vw` to `100%` (prevents horizontal overflow) 3. **Visual appeal** — gradient background, shadow effects, smooth transitions 4. **Interactivity** — hover effect on the circle 5. **Accessibility** — added `role="img"` and `aria-label` 6. **Semantics** — better title, ID, and HTML structure 7. **Typography** — system font stack for better rendering The circle is now centered, visible, and responds to hover with a subtle visual change.
