what changed from step 049
Nothing. The file is byte-identical to step 049.
What the model said
I didn't change `0.html` yet. It's an empty page skeleton with no content inside `<main>`, and the base setup is already solid: viewport and color-scheme meta tags, box-sizing reset, readable line length, balanced text wrapping, visible focus styles and reduced-motion support. A few small things could still be added: - **A real `<title>`** (right now it's just "0") and a `<meta name="description">`. - **`min-height: 100dvh` on body** and `hyphens: auto` for long words on narrow screens. - **Default styles for common elements** like `code`/`pre`, tables, `a` link colors and `hr`, plus `:where()` to keep specificity low. - **A `<header>`/`<footer>` layout** or a skip link, if the page will have navigation. What is this page going to be (a landing page, an article, a form, a tool)? If you tell me, I'll build it out properly. Or I can just apply the small fixes above.
