 **Automatic Event Summaries:** When your event is shared on the Fediverse, platforms like Mastodon that don't fully support events will display a brief HTML summary of key details — such as the event's title, start time, and location. This ensures that even if someone can't view the full event on their platform, they still get the important info at a glance, with a link to your WordPress event page.
