## Prompt

Create a 290px card that sets color-scheme: light dark and uses the light-dark() function for every color: background light-dark(#fafaf9,#1c1917), text light-dark(#1c1917,#fafaf9), border 1px light-dark(#e7e5e4,#44403c), shadow alpha .06 in light and .4 in dark, muted text light-dark(#57534e,#a8a29e). 14px radius, 22px padding, 18px title, 14px paragraph, and a small button whose background and text colors invert between modes (dark button in light mode, light button in dark mode), 85% opacity on hover.

## HTML

```html
<article class="card-049">
  <h3>light-dark() in one line</h3>
  <p>Each color declares both values; the browser picks based on color-scheme.</p>
  <a href="#">Read the spec</a>
</article>
```
