Whether a presence transition (arrival: login / reconnect — or
departure: logout / disconnect) surfaces to the viewer. A presence
frame renders inline in the message buffer like any other scene frame
(there is no separate notification surface), so the choice is binary:
show it, or stay silent. The frame's tint comes from the rule
color; the specific verb (entered / reconnected / left / dropped)
comes from the event, not this field.
