/**
 * CTA Optimization System - Bay Area Golf
 *
 * Based on Booking.com/Expedia conversion best practices:
 * - Large touch targets (min 48px for mobile per Google Material Design)
 * - Clear visual hierarchy between primary, secondary, tertiary actions
 * - Comprehensive button states (hover, active, focus, disabled, loading)
 * - Subtle urgency without being pushy
 * - Trust signals and social proof integration
