What the model said
I made one change to `0.html`: the browser tab icon is now a small black circle instead of a blank placeholder. The icon is built into the file, so there's no extra file to load. I haven't opened it in a browser to check. I left everything else alone because it already works well: - It's marked up correctly and screen readers will read the circle as "Black circle." - The circle resizes to fit small screens. - It stays visible in Windows high-contrast mode. - It stays centered on mobile browsers. If you had something else in mind, like animation, a dark mode or a different size, tell me what you want and I'll add it.
