OpenGraph Fallback Embed adds a custom Gutenberg block and an auto-embed fallback that renders rich link cards using OpenGraph metadata from any URL.
Features:
<ul>
<li>OpenGraph Embed block — Paste any URL to embed it as a styled card showing the page’s title, description, image, and site name.</li>
<li>Auto-embed fallback — When WordPress can’t find an oEmbed provider for a URL pasted on its own line, this plugin automatically fetches the page’s OpenGraph tags and renders a card instead of a plain link.</li>
<li>Graceful degradation — Falls back to Twitter Card meta tags, then to HTML <code><title></code> and <code><meta name="description"></code> when OpenGraph tags are missing.</li>
<li>Transient caching — Fetched metadata is cached for 7 days to minimise external requests.</li>
</ul>
<h3>Development</h3>
