How to read this site

Nine chapters on the left. The argument runs end to end if you read it sequentially, but every chapter stands on its own — jump in wherever the question you're holding lands. The diagnosis (chapters 1, 2), the architecture (3, 4), the economics (5, 6), the human shape (7, 8), the reference shelf (9). Most of the book is open. A few nodes — the high-value commercial detail, the formal math — sit behind a progressive gate that asks a couple of questions about who's reading.

SAGE is on the right. Real conversational AI scoped to this book's twelve concept documents plus the glossary. Ask it anything about what you're reading. It can compare VYAN to your existing stack at an architectural level, walk you through a specific chapter, route you to the part of the book that maps to your role, or start a PULSE benchmark on your planning organization. It refuses cleanly when a question is outside its scope — that discipline is the same one VYAN's in-product SAGE follows by design.

Most terms in the prose carry an inline hover for a short definition plus a link to the full glossary entry. The glossary opens as an overlay from the top bar so you don't lose your place. PULSE — VYAN's planning-maturity benchmark — surfaces inline at a few specific moments where it answers the question you'd otherwise be asking. Pane widths are adjustable. Cmd+\ and Cmd+. collapse the side panes.
