## 外掛說明
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`
` and `<meta name="description">` when OpenGraph tags are missing.
* **Transient caching** — Fetched metadata is cached for 7 days to minimise external
requests.
### Development
The source code for this plugin, including unminified JavaScript and CSS, is available
on GitHub:
[OpenGraph Fallback Embed on GitHub](https://github.com/pento/opengraph-fallback-embed)
The plugin uses [@wordpress/scripts](https://developer.wordpress.org/block-editor/reference-guides/packages/packages-scripts/)
for building. Source files are in the `src/` directory. See the repository README
for build instructions.

## 常見問題集
### What happens if a URL has no OpenGraph tags?
The plugin falls back to Twitter Card meta tags, then to the page’s `<title>` and`
<meta name="description">`. If none of these are available, the original WordPress
output is preserved.
### Does this override existing embed providers?
No. This plugin only activates when WordPress has no other embed handler for the
URL.
### Can I customise the card appearance?
The card uses the `.og-fallback-embed` CSS class. You can override styles in your
theme.
