The rhythm
How often, where, and in what form.
The part
What it is
Stated per channel, because each has a different tolerance. The same cadence that builds a habit in one place reads as silence in another.
A rhythm the audience can predict is worth more than a higher volume they cannot.
The smallest level
The attributes it carries
Each attribute is one of the framework’s shared types. What a date is, and how it is written, is defined once for the whole model — the note here says what it means in this particular place.
