/**
 * EC-IELTS DESIGN SYSTEM
 * 
 * Unified design system with centralized tokens in /static/css/tokens/
 * This file serves as the main stylesheet and component definitions.
 * 
 * Token Hierarchy:
 * 1. /tokens/base.css - Core design tokens (colors, spacing, typography, effects)
 * 2. /tokens/light-theme.css - Light mode refinements
 * 3. /tokens/dark-theme.css - Dark mode refinements
 * 4. /tokens/legacy-compat.css - Backward compatibility layer for existing code
 * 5. design.css (this file) - Component styles and utilities
 * 
 * Multi-Tenant Branding:
 * - Tenant-specific colors flow through context processor
 * - Brand tokens override base accent color
 * - Theme system applies after branding
