/* ============================================
   duktus — Matte Ceramic · Shared brand components
   SINGLE SOURCE OF TRUTH for the cross-surface TopBar + Footer.
   Self-contained: depends ONLY on tokens.css custom properties.
   Mirrors the marketing reference (src/shell.jsx) 1:1 so tools, docs
   and status render an identical bar + footer.
   Edit HERE only, then run `npm run brand:sync`.
