"""Where the milliseconds of a voice turn go.

One number decides whether any of the voice work was worth doing: how long
between someone stopping talking and Bea's first sound. Everything else — a
streaming TTS, a push channel, a reflex — is a bet on moving that number, and a
bet nobody can read is a bet nobody can settle.

So the turn carries a stopwatch from the moment audio lands to the moment the
first byte leaves for the call, and the breakdown says which stage to blame.
