/**
 * BV WooCommerce Attribute Sets - Frontend Styles
 * 
 * =========================================================================
 * CUSTOMER INTERFACE STYLING
 * =========================================================================
 * This stylesheet creates an intuitive, visually appealing interface for
 * customers to configure products using the plugin's attribute hierarchy.
 * The design focuses on clarity, ease of use, and mobile responsiveness.
 * 
 * DESIGN GOALS:
 * • Clear visual hierarchy that guides customer choices
 * • Intuitive selection states and feedback
 * • Mobile-first responsive design
 * • Integration with popular WooCommerce themes
 * • Accessibility compliance (WCAG 2.1 AA)
 * • Performance optimization (minimal CSS, efficient animations)
 * 
 * CUSTOMER EXPERIENCE PRINCIPLES:
 * • Progressive disclosure - show relevant options based on selections
 * • Clear pricing feedback - immediate visual indication of price changes
 * • Visual confirmation - selected states clearly indicated
 * • Error prevention - disable invalid combinations
 * • Mobile optimization - touch-friendly interfaces
 * 
 * COMPONENT STRUCTURE:
 * 1. Main Container - Overall attribute selection interface
 * 2. Attribute Sets - Logical choice categories (LEGS, SEAT, etc.)
 * 3. Price Groups - Pricing tiers within each category
 * 4. Selection Interface - Radio buttons, dropdowns, color swatches
 * 5. Modal System - Overlay for complex selections
 * 6. Price Display - Dynamic pricing updates
 * 7. Mobile Optimization - Responsive breakpoints and touch UI
 * 
 * VISUAL STATES:
 * • Default - Available for selection
 * • Selected - Currently chosen option
 * • Hover - Interactive feedback
 * • Disabled - Not available based on other selections
 * • Loading - Processing state during AJAX operations
 * 
 * THEME INTEGRATION:
 * Designed to work seamlessly with popular WooCommerce themes while
 * maintaining the plugin's visual identity and functional requirements.
