What the model said
`0.html` is an empty starter template: `<main>` has no content, and the base setup (viewport, color-scheme, box-sizing, focus styles, text wrapping) was already good. I made one change. The reduced-motion rule used `animation: none` and `transition: none`, which can break scripts that wait for `animationend` or `transitionend` events. It now shortens durations to near zero instead, so those events still fire. What should the page be? Things I could add: - **Content:** a real `<title>`, a `<meta name="description">`, and a header, main content and footer. - **Styling:** a colour palette with light and dark themes, a type scale, and link and button styles. - **A specific purpose:** such as a landing page, a document or an app shell.
