What the model said
I made a few small changes to `0.html`. The page was already well built, so there wasn't much to improve: - **Added `theme-color`:** mobile browsers now color their toolbar white to match the page. - **Added `description`:** search results and link previews now have a short description of the page. - **Removed `overflow: visible` from the SVG:** the circle already fits exactly inside its viewBox, so this rule wasn't doing anything. The circle looks the same as before. If you had a different kind of improvement in mind, like styling, animation or dark mode, tell me which.
