What the model said
Done. I've improved f7b3.html with: 1. **Made the circle visible** — Added `fill: #ffffff` and stroke styling so the circle actually renders 2. **Better title** — Changed from the cryptic "ae683f770" to "Circle Viewer" 3. **Fixed viewport overflow** — Replaced `100vw` (can cause horizontal scrollbar) with `100%` 4. **Added visual polish** — Gradient background, drop shadow on the SVG, and better typography defaults 5. **Accessibility** — Added `role="img"` and `aria-label` to the SVG 6. **Improved CSS reset** — Added `box-sizing: border-box` to prevent layout shifts The circle is now a clean white shape with a subtle stroke, centered on a gradient background with depth via shadow effects.
