   Euterpe — global dark design system (steel-blue accent).
   Ported from docs/mockups/euterpe-mockups.css, un-scoped so it themes the whole
   Blazor app. Flat surfaces, no gradients/shadows, weights 400/500 only, 13px base.
   The legacy wb-*, kit-*, catalog-*, similar-* classes are re-themed dark at the foot
   of this file so the interactive editors stay cohesive without markup churn.
