This post verifies link cards: bare links standing alone as their own paragraph turn into OG preview cards, while inline links keep their normal style.

## Positive cases: sites with OG metadata

https://astro.build/

## Negative cases: a 404 and a site without OG (should fall back to plain links; the build must not fail)

## Inline links keep their normal style (must not become cards)

Here is an inline link, [the official Astro site](https://astro.build/), set in the middle of a sentence; it must keep its normal link style — the page must not turn into a wall of cards.

## Card via first-line text (the markdown link form triggers it too)
