  Editorial Workbench — reusable design + motion library
  Extracted from outputs/stem-agent-orchestration-website-style.html (2026-08-26).
  Paper/ink/cobalt/red/yellow editorial system: bordered "plate" surfaces with hard
  offset shadows, condensed display type, mono labels, and a small set of
  data-attribute-driven motion primitives (reveal / stagger / sequence / draw / lift).

  SSoT: design/styles/editorial-workbench/workbench.css
