/* Deliverable Configuration UI (CC-SPEC-DeliverableConfigUI.md §7).
   A dedicated global stylesheet (NOT component-scoped) so the dc-* classes apply
   across the whole component family — avoids the scoped-CSS gotcha that made the
   prior catalog look unstyled. Uses the global Ivaro tokens (SharedUI app.css):
   --color-*, --space-*, --text-*, --font-*; fallbacks keep it robust if a token
   is missing. Sentence case, two weights, no shadows/gradients. */
