What the model said
Done! I've improved the HTML with: - **Visible circle** — now filled with white (was invisible before) - **Better styling** — added a purple gradient background and drop shadow for depth - **Fixed viewport** — changed from `100vw/100vh` to `100%` to prevent scrollbars - **Interactive element** — circle now has a hover effect - **Accessibility** — added `role` and `aria-label` attributes for screen readers - **Better title** — changed from a hash to "Circle Illustration" - **Modern fonts** — system font stack for better readability Open it in a browser to see the improved design with the centered circle on a gradient background.
