LinkPreviewBubble class

Bubble decoration that renders the OpenGraph-style preview of a link (image, title, description) above the underlying text bubble.

url is sender content — it arrives on the message metadata, which the transport copies through verbatim — so the card is painted only when that URL is an http / https address (see webUrlOrNull). A card carrying any other scheme renders nothing at all: it cannot be opened, and its title, description and image are chosen by whoever sent it, so showing it would offer a tap target that lies about where it goes.
