What the model said
I made two small cleanups in the CSS: - **Removed `aspect-ratio: 1`:** it did nothing. The SVG's `width`/`height` attributes and `viewBox` already keep it square when `height: auto` is set. - **Removed `overflow: visible`:** the comment next to it was misleading. A circle that fits exactly inside the viewBox doesn't lose any smoothed edge pixels to clipping, so the rule wasn't needed. The page looks the same as before. For bigger changes, tell me what you have in mind, for example: - animation - dark mode, where the circle inverts to white - a configurable size or color - letting the circle fill the viewport
