Nothing. The file is byte-identical to step 042.

What the model said

I looked at `0.html` and didn't change anything. It's an empty starter page, and the base is already solid: it has the viewport and color-scheme settings, a CSS reset, readable text width, visible keyboard focus and reduced-motion support. `<main>` is empty and the title is just "0".

The only small fixes that make sense without knowing its purpose are:
- a real `<title>` and a `<meta name="description">`
- `-webkit-font-smoothing` and `hanging-punctuation` for nicer text
- a `<noscript>` or skip link, if it will have navigation

What should this page be (a landing page, an article, a form, an app shell)? Once I know, I can add the content, layout and styling.
