Everything here is current and canonical. The Compendium is the complete reference; the brochure is the designed short-form; the decks carry the same story in presentation form.
The complete reference: why, what, how it works, boundaries, governance, all sixteen FAQ answers, and how to join. Ten pages.
The same document in editable form.
The designed ten-page print piece, photography included.
Twelve slides: the case for joining, for a first meeting.
Twenty-one slides: the full story for workshops and onboarding.
