What the model said
`0.html` was already in good shape. It has valid markup, an accessible SVG title, and a circle that stays centered and resizes with the screen. I made two small changes to make it sturdier: - **Added `width="400" height="400"` to the SVG.** If the CSS fails to load, the circle now shows at a sensible size instead of the browser's default. When the CSS does load, it still controls the size. - **Moved the black fill onto the circle itself** (`fill="#000"`) and deleted the matching CSS rule. This keeps the color with the shape, so the SVG looks right even if it's copied out on its own. Nothing changes visually. If you had something else in mind, like dark mode support, animation, or another size or color, tell me and I'll do that.
