OpenGraph Fallback Embed

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:

• OpenGraph Embed block — Paste any URL to embed it as a styled card showing the page’s title, description, image, and site name.
• 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.
• Graceful degradation — Falls back to Twitter Card meta tags, then to HTML <title> and <meta name="description"> when OpenGraph tags are missing.
• Transient caching — Fetched metadata is cached for 7 days to minimise external requests.
