/**
 * Order Daemon Design System - Shared Foundation
 * 
 * Three-tier design system providing consistent styling across all Order Daemon components.
 * This file contains the foundational design tokens and semantic variables used by both
 * the insight dashboard and rule builder components.
 * 
 * Three-Tier Architecture:
 * 1. PRIMITIVES: Raw, context-free values (colors, fonts, spacing)
 * 2. SEMANTICS: Generic, purpose-driven variables (component blueprints)
 * 3. COMPONENTS: CSS classes that apply semantic variables with theme overrides
 * 
 * @package OrderDaemon\CompletionManager
 * @since   2.0.1
