what changed from step 061
Nothing. The file is byte-identical to step 061.
What the model said
I didn't change anything. `0.html` is already in good shape for what it does, which is show one black circle in the middle of a white page: - It has the right basics: doctype, language, charset, viewport, description, title and favicon. - The circle stays centred with `display: grid` and `place-items: center`, and `100dvh` handles mobile browser toolbars. - It resizes to fit small screens (`min(400px, 90vmin)`), and the fixed width and height stop the layout from jumping while it loads. - Screen readers get a label from `role="img"` and the `<title>`. - High-contrast mode is handled with the `forced-colors` rule. Anything I added would be a change for its own sake. If you have something specific in mind, I can do it, for example: - **Dark mode:** a white circle on black when the system is set to dark. - **Animation:** a subtle pulse or fade-in that stays still for people who've turned on "reduce motion". - **Interaction:** the circle responds when you hover over or click it. - **Content:** turn the page into something more than one circle. Which way do you want to take it?
