/* ── Enterprise Workflow Engine — generic reusable components ───
   Task Inbox / Action Bar / Timeline. Entity-agnostic: styled purely from
   existing design tokens (variables.css) and existing badge/button
   components — no new colors, no new type scale. First consumer is
   Documents; any future module (Procurement, Service Desk, HR, ...) reuses
   these same classes unchanged. */
