investigate adding support for responsive images

To Do: investigate adding support for responsive images (`` element and `srcset` prop)

Handle resolution switching:
```html

````

Handle art direction:
```html

```

see: https://developer.mozilla.org/en-US/docs/Learn/HTML/Multimedia_and_embedding/Responsive_images

Start with the linked MDN responsive-images guide and the two HTML examples in the issue. Identify the library entry points and tests affected by supporting the element, srcset resolution switching, and art direction; done means the supported API and expected behavior are defined and verified.
