/* ==========================================================================
   Workbench — shared shell styles for interactive demos
   Extends the Field Notebook design system (DESIGN.md).
   Reuses tokens from /assets/colors.css and components from /styles.css.
   Do NOT fork the design system; this file only adds Workbench-specific shell
   classes and demo-stage framing.

   Architecture (two-layer):
   1. Workbench Shell  — identical on every demo, owns ALL real navigation.
      Classes: .wb-shell, .wb-breadcrumb, .wb-toolbar, .wb-toolbar__blurb,
               .wb-toolbar__actions, .wb-stage, .wb-footer
   2. Demo Stage       — per-demo costume (Notion now, maybe Linear/terminal later).
      Lives inside .wb-stage; the shell is app-agnostic.

   To add a new demo:
     1. Copy /tools/control-loop-board/ as /tools/<slug>/
     2. Fill the shell slots: breadcrumb name, toolbar blurb, source-post link,
        subscribe CTA, per-demo actions.
     3. Build your stage inside .wb-stage.
