What the model said
I made a handful of targeted fixes to `0.html`; the page was already in good shape, so I left the design alone. I haven't opened it in a browser to check the result. ## What changed - **Clipping on hover:** the circle (radius 190 plus stroke) scaled by 1.05 grew past the 400-unit viewBox, and the bouncy easing overshoots further, so the edges were cut flat. The radius is now 180 and the SVG has `overflow: visible`. - **Opacity snap:** only `transform` was transitioned, so the opacity jumped from 0.9 to 1. It now fades. - **Hover target:** the effect fired on the whole SVG box, including the empty corners. It now fires only over the circle itself. - **Touch feedback:** added `:active` so tapping gives the same response as hovering. - **Reduced motion:** those users previously got no feedback at all. They now get the opacity change, without the scale. - **Redundant stroke:** removed, since it was the same colour as the fill and only added to the radius. - **Dark mode shadow:** raised from 0.3 to 0.6 alpha, as it was barely visible against the `#111` background. - **Transform origin:** added `transform-box: fill-box` so the scale is centred on the circle itself. ## Left as is The title and `aria-label` call this "animated" and "interactive", but the only motion is the hover effect. I didn't add an idle animation or reword the text, since either is a design call — say if you want one of them.
