how the mvp stays in sync
1 · controller

the only device allowed to set the starting point, start, stop, and reset.

2 · local relay

a discoverable WebSocket service assigns order and rebroadcasts timestamped state.

3 · followers

estimate clock offset, then render locally from an agreed future start time.
