/* ============================================
   DARK MODE SUPPORT
   ============================================
   Dark mode is handled automatically by the Designer system.
   When .es-mode-dark or .ensemble-dark-mode class is applied,
   the --ensemble-* variables are overridden with dark values
   by the ES_CSS_Generator PHP class.
   
   Available dark variables:
   --ensemble-dark-primary, --ensemble-dark-text,
   --ensemble-dark-card-bg, --ensemble-dark-border, etc.
   
   See CSS-ARCHITECTURE.md for full reference.
