/**
 * ============================================
 * RECOMMENDATIONS.CSS
 * ============================================
 *
 * Dedicated stylesheet for product recommendations sidebar
 *
 * PURPOSE:
 * - Provides production-ready styles for the recommendations sidebar
 * - Implements industry-standard 70/30 chat-to-sidebar layout ratio
 * - Fixes scrolling issues with proper height constraints
 * - Ensures professional alignment and spacing throughout
 *
 * KEY FEATURES:
 * 1. CSS Variables: Centralized design system for easy customization
 * 2. Proper Scrolling: Independent scroll areas prevent parent interference
 * 3. Accessibility: Keyboard navigation and ARIA attributes supported
 * 4. Responsive: Smooth animations and hover states
 * 5. Toast Notifications: User feedback for copy-to-clipboard actions
 *
 * ARCHITECTURE:
 * - Uses 8px base grid system (0.5rem increments) for consistent spacing
 * - 70/30 split between chat and sidebar (industry best practice)
 * - Height calculations use CSS variables for maintainability
 * - Prevents scroll bubbling with touch-action and overscroll-behavior
