How it fits. The emote already travels in the pose; what is missing is a shared clock. The server can publish a beat epoch in the welcome, or include one in the event state, so every client quantizes to the same grid. The avatar animation already runs from a local phase in liuverse-world::avatar; snapping that phase is a local change. The director can hear "crowd dancing" as a mood, the same way it hears a vehicle.

Scope.

A server-owned beat epoch, carried once and re-synced like the event clock.
Quantize an emote's start to the next beat when another emote is already running nearby.
A crowd mood for the music director, with a matching tempo.
Keep solo emotes loose; only nearby groups snap.
No new per-frame wire traffic.

Related. #168 (busking), #204 (karaoke), #205 (greetings).

Emotes start when each client first sees them, so a group dance is a pile of different phases. The fix is a shared beat: when two or more players emote within earshot, snap the performances to a common phase and let the music director pick a take at that tempo. A flash mob becomes possible without anyone organising it. **How it fits.** The emote already travels in the pose; what is missing is a shared clock.
