The voice: every game speaks in its own world

Conventions gain a section on in-game language: an image with every
fact, the fact exact, unfolding effects told a turn at a time and naming
the turn they end on, our own words rather than an older version's, and
chronicle wording shipped without a rules revision. new-game.sh points
at it, and the demo game's lines follow it. Born in Waving Hands'
atmospheric chronicle.
