what changed from step 050
Nothing. The file is byte-identical to step 050.
What the model said
I looked at `0.html` and didn't change anything. It's already a solid starter page: the right meta tags, `lang`, dark-mode support, readable line length, reduced-motion handling and visible keyboard focus. The only real gap is that `<main>` is empty, so there's no content to improve yet.
Small additions that would help:
- **A real `<title>`** and a `<meta name="description">`. Right now the title is just "0".
- **`body { min-height: 100dvh; }`** if you plan to add a footer or centre content on the page.
- **`textarea { resize: vertical; }`**, and **`a { text-underline-offset: 0.15em; }`** so underlines sit a little lower and read better.
What do you want the page to be (a landing page, an article, a tool, or a reusable template)? Tell me and I'll build it out, or say the word and I'll just apply the tweaks above.
