What do you mean by banner?

Maybe a banner to show that it's a beta content? There're also concerns from official Discord that people searched up for information and accidentally found out the new beta event in the Explorations page, without willing to know. There should be some way to prevent people from knowing beta, when they're not beta testers. I suggest that beta contents should be briefly explained in the Beta page first, and they will have a dedicated page once it's out to public. For example, the new event info can be removed from the Explorations page and instead moved to Beta page.

I was under the weather, and this is the first day I came back to the wiki after a week break. As a proper reply from the question, the banner should be created as an image before being uploaded and used in the pages.
