/* design-system.css - CreditChain's institutional-web3 design system.
   Phase 1 of the full brand/product redesign: tokens + core reusable
   components, applied first to one representative page per visual
   family (index/wallet/explorer/login) for review before rolling out
   to the remaining pages. See the design directive for the full
   rationale - this file is the "establish the system first" half of
   it.

   Loaded AFTER theme.css and BEFORE style.css/outernet.css on every
   page it's added to: this file's :root block re-defines theme.css's
   existing --cc-* tokens to the new brand values, so every existing
   rule across style.css/outernet.css that already reads --cc-bg-1,
   --cc-accent-1, etc. re-themes automatically, with zero changes to
   those files and zero risk to the markup/JS they style. New
   selectors/IDs are never required by this file - everything here is
   additive (new tokens, new component classes) or a re-definition of
   an existing token, never a redefinition of an existing component
   class from style.css/outernet.css. */
