/**
 * NeuroTouch Hero Section Styles
 *
 * Custom styling for the NeuroTouch Symmetry Serum hero section pattern
 * Fills viewport width, 8px rounded corners
 * Overlay layout: text overlays image on all breakpoints
 * Desktop: 120px left padding, 0 right padding, max-width 600px content
 * Content column: >= 64px margin top/bottom (left side only)
 * Desktop: Image positioned absolutely, extends across both columns with overflow hidden
 * Mobile gradient: top to bottom; Desktop gradient: left to right
 * Mobile: 250px max button width
 *
 * @package eride
 * @version 2.3.0
 *
 * Changelog:
 * 2.3.0 (2025-12-09) - Cache bust for deployment (matches loader v4.16.0)
 * 2.2.0 (2025-12-09) - Requirements update per NEUROTOUCH-HERO-UPDATE.md
 *       - Updated container max-width from 1400px to 1440px for proper header alignment
 *       - Enhanced gradient with 8 intermediate stops for smoother transition (reduces banding artifacts)
 *       - Applied multi-stop gradient to both desktop (horizontal) and mobile (vertical) layouts
 *       - Improved visual quality with high-fidelity color transitions
 * 2.1.0 - Image extends across columns: Absolute positioning allows image to grow
 *         with viewport width, overflow hidden clips excess for clean edges
 *       - Removed flex constraints on image container (now position: absolute)
 *       - Image uses object-fit: cover with center-left positioning
 * 2.0.0 - CSS Modernization: Migrated to design system variables
 *       - Replaced hardcoded colors with CSS custom properties
 *       - Added transition variables for consistent animations
 *       - Added shadow variables for modal overlay
 *       - Retained !important for WordPress FSE block overrides (necessary)
 *       - Improved maintainability with centralized color management
