what changed from step 027
Nothing. The file is byte-identical to step 027.
What the model said
I didn't change anything in `0.html` because it's already in good shape. It's a single black circle that stays centred and scales to fit any screen. It has an accessible title for screen readers, handles high-contrast mode, and has a matching favicon. Anything I could add now, like a meta description or a `theme-color` tag, would just be busywork. "Improve" could mean a few different things here, so tell me which you want: - **Visual:** animation (pulse, breathing), a gradient or shadow, or a dark-mode version with the colours swapped. - **Interactive:** a click to change colour, or a circle that follows the cursor or can be dragged. - **Purpose:** turn it into something specific, like a loading spinner, a logo, or a generative-art piece. - **Code:** cut it down to the smallest possible file, or change it to CSS-only with no SVG.
