/* ========================================
   DESIGN TOKENS - Single Source of Truth
   ========================================
   All color, typography, spacing, and effect values.
   Import this file FIRST in every HTML page.
   
   HOW TO USE:
   - Reference tokens as var(--token-name)
   - Never hardcode hex values in other CSS files
   - Add new tokens here, not in page-specific files
   
   ORGANIZATION:
   - Brand Colors: Primary orange, secondary teal
   - Surface Colors: Backgrounds for different contexts
   - Text Colors: Hierarchy from primary to muted
   - Border Colors: Subtle to strong opacity levels
   - Status Colors: Success, warning, danger, info
   - Typography: Fonts, sizes, weights
   - Spacing: Consistent scale from 4px to 96px
   - Effects: Shadows, transitions, z-index
