   IGNY8 UTILITY CLASSES & LEGACY SUPPORT

   ⚠️  DEPRECATED: This file is maintained for backward compatibility.
   New code should use:
   - CSS variables: var(--color-primary), var(--color-success), etc.
   - Tailwind utilities: bg-brand-500, text-brand-500, etc.
   - React components: Button, Badge, Card from /components/ui/
   
   🔒 DESIGN SYSTEM LOCKED - See DESIGN_SYSTEM.md for complete style guide
   
   This file provides:
   1. Legacy variable aliases (--igny8-* → --color-*)
   2. Active utility classes (.igny8-table-*, .igny8-header-metric-*)
   3. Deprecated utility classes (marked below - do not use in new code)

   DEPRECATED UTILITY CLASSES
   ===================================================================
   ⚠️  DO NOT USE IN NEW CODE
   These classes are deprecated. Use Tailwind utilities or React components instead:
   - .igny8-bg-blue → bg-brand-500 or bg-[var(--color-primary)]
   - .igny8-text-blue → text-brand-500 or text-[var(--color-primary)]
   - .igny8-border-blue → border-brand-500 or border-[var(--color-primary)]
   
   Migration: Replace with Tailwind utilities or use Button/Badge/Card components.
