What is the purpose of the <picture> tag?
<picture> allows serving different image versions depending on device, screen size, or
media type.
Example:
<picture>
<source srcset="photo-large.jpg" media="(min-width: 800px)">
<source srcset="photo-small.jpg" media="(max-width: 799px)">
<img src="photo-default.jpg" alt="Beautiful landscape">
</picture>
Key Takeaway:
Use <picture> for art direction — showing different images per device or context.
