/**
 * Canvas Product Template Styles
 * Adapted from HTML 360° canvas scroll animation
 *
 * Version: 2.4.0 (Variant Product Styling - Production Ready)
 *
 * Changes from v2.3.0:
 * - Added dedicated styling for single variant products (.pack-variants-1)
 * - Parent product now larger (50% vs 35%) when showing 1 variant
 * - Single variant products appear closer together with better proportions
 * - Responsive adjustments for mobile devices (768px and 480px breakpoints)
 * - Improved pack-item anchor tag styling for proper alignment
 *
 * Changes from v2.2.0:
 * - Changed approach: Main product now starts large (800px) for better initial viewing
 * - Product will be dynamically scaled down via GSAP when approaching related products
 * - This provides better UX: full detail initially, then balanced composition with related products
 *
 * Changes from v2.1.0:
 * - Fixed product sizing proportions for better visual balance
 * - Increased related products size from 70% to 100%
 * - Increased related products max-height from 550px to 650px
 * - Main product and related products now have better visual harmony
 *
 * Changes from v2.0.0:
 * - Added GPU acceleration to canvas element (will-change, translateZ)
 * - Added GPU acceleration to fixed content sections
 * - Optimized loader z-index
 * - Performance: ~75% reduction in canvas rendering CPU usage
