Nothing. The file is byte-identical to step 048.
What the model said
I read `0.html` and made no changes. It's a black circle on a white page, and it's already well built: - **Layout:** it's centered with `dvh`, which handles mobile browser toolbars, and it resizes with `min(400px, 90vmin)`. - **Accessibility:** the SVG has `role="img"` and a title, and it still shows up in high-contrast mode (`forced-colors`). - **Page setup:** it has the viewport meta tag and an inline favicon, and it doesn't load any other files. The only thing I'd consider removing is `overflow: visible` on the SVG, which does nothing here. That's too small to count as an improvement, so I left it alone. What kind of improvement do you want? For example: - **Dark mode:** a white circle on a black background when the system uses a dark theme. - **Visual polish:** a gradient, shadow or subtle animation. - **Configurable:** set the size and color through CSS variables or the URL. - **Something else:** a different shape, or turning it into a loading spinner.
