What the model said
Done. I've improved the file with: - **SVG namespace** added for valid markup - **Visible circle** with white fill (was invisible before) - **Responsive layout** using `max-width/max-height` instead of fixed pixels - **Fixed viewport issue** (`100%` instead of `100vw` prevents scrollbars) - **Visual polish**: gradient background, drop shadow, better IDs and title - **Accessibility**: added system fonts The circle is now visible and scales responsively. Want me to test it in a browser?
