HoF: Events are also not as screenshottable as I would like. #6536

This massively under-sells the results.

We should extend the event schema to allow event hosters to share numbers back with us. Then instead of "5 events" we could say "4,102 registrations across events".

And we should include some icons for countries / global where appropriate, and online/in person to make it more visually appealing even if that isn't actionable information.
