/* =============================================================================
   build-wizard.css — the Emergent "Build your system" wizard design, ported
   verbatim for the live server-rendered /build (setup_review.html) flow.

   Self-contained on purpose: it carries its own obsidian+brass token layer and
   button primitives so the wizard page needs only fonts.css + this file, and so
   it NEVER touches the contended static/ledger.css. Font faces come from
   fonts.css (Inter Tight + Cormorant Garamond, self-hosted). The live 6-step /
   37-field form contract is unchanged — this is presentation only.
   Source: Emergent gcs_gcs_ui.zip (src/index.css :root + src/App.css .build__*).
   Doctrine: brass = money/active/focus only; the single primary action is ivory.
