What the model said
**Changes made:** 1. **Visible circle** — Added `fill: #fff` and `stroke` to render the shape 2. **Fixed layout** — Changed `width: 100vw` to `width: 100%` (prevents horizontal scrollbar) 3. **Enhanced styling** — Added a purple gradient background, drop shadow, and improved visual hierarchy 4. **Better semantics** — Changed title from hash to "Circle", added `box-sizing: border-box` 5. **Polish** — Added system font stack and stroke styling for definition The page now displays a clean white circle with proper shadow on a gradient background.
