What the model said
**Improvements made:** 1. **Circle now visible** — Added blue fill (#2563eb); was invisible before 2. **Fixed viewport issue** — Changed `100vw` to `100%` + `overflow: hidden` (100vw causes horizontal scrollbars) 3. **Better semantics** — Added SVG `xmlns`, improved ID and title, added `aria-label` 4. **Visual polish** — Light background for contrast, drop-shadow, hover effect (circle darkens on hover) 5. **Smooth interaction** — CSS transition on fill color change 6. **Font stack** — System UI fonts for consistency Open it in a browser to see the circle render with a subtle shadow and hover effect.
