Overview

Poll, plus a content-free nudge broadcast on transition so clients re-poll immediately instead of waiting for the next interval — near-instant latency with the same server-filtered (arbitrary-visibility) delivery. The nudge carries no identity/state, so it only reveals "activity happened".
