What the model said
Done. Key improvements: - **Visible circle** — added white fill + stroke styling - **Fixed layout** — changed `100vw` to `100%` to prevent horizontal overflow - **Better styling** — gradient background, drop shadow, cleaner appearance - **Accessibility** — added `role` and `aria-label` to SVG - **Cleaner metadata** — meaningful title, removed cryptic IDs - **Better defaults** — `overflow: hidden`, font stack, proper viewport The circle is now visible with a modern gradient background and drop shadow.
