## Prompt

Build a card that responds to its container, not the viewport. Wrap it in a div with container-type: inline-size. The card is white with a 1px #e5e7eb border and 14px radius, stacked by default (160px image on top with 135deg gradient #a7f3d0 to #0d9488, then a body with 17px title and 14px #6b7280 text). Under @container (min-width: 400px) switch to a row with a fixed 180px image column and bump the title to 20px.

## HTML

```html
<div class="card-069-wrap" style="width:520px">
  <article class="card-069">
    <div class="card-069__img"></div>
    <div class="card-069__body"><h3>Sized by the parent</h3><p>Resize the wrapper below 400px and this card stacks vertically.</p></div>
  </article>
</div>
```

## CSS

```css
.card-069-wrap{container-type:inline-size;max-width:100%}
