Add preview metadata for X and Twitter-style link cards.

How does the head control X/Twitter link cards?

Twitter card meta tags tell X/Twitter-style platforms what card type, title, description, and image to use when the page is shared.

Open Graph handles many sharing previews, but some platforms also read Twitter card metadata.

These tags are similar to Open Graph, but they use name="twitter:..." instead of property="og:...".

The goal is the same: make the shared page preview clear, honest, and useful.

The most common card type for a visual preview is summary_large_image.
