Steps to reproduce the problem

I was reading Mastodon.social via the Android app Tusky. I saw this

I was surprised. Had I found a bug in Tusky? So I opened mastodon.social in a web browser and I scrolled down to the Greg Parker message:

Oh. That thing.

It appears your new "Wrapstodon" thing uses a unique notification type which third-party clients seem to require specific support for. As a member of the Tusky project, I have questions:

• What is the notification type? Is it documented? Will it be documented?
• Is this notification type something that will recur again, besides this one-off event on December 2, 2024? If so is it specific to your yearly "wrapstodon" event or or is this actually some kind of general server-staff announcement notification type that might be important for other purposes as well?

We have not attempted to perform manual debugging such as extracting the returned notification JSON.
