   AFFILYNC DESIGN TOKENS - Single Source of Truth
   Financial Edge Design System

   This file consolidates ALL design token definitions
   from the previously fragmented sources:
   - design-system.css (:root variables)
   - index.css (@layer base variables)
   - utilities.css (opacity variables)
   - components.css (z-index component variables)
   - layout.css (layout z-index classes)

   Import this file FIRST, before any other CSS.
   Other files should REFERENCE these tokens, not redefine them.
