/**
 * SantaTheme Scroll Animations
 *
 * Reusable scroll-triggered animations for pages and posts.
 * Add the appropriate class to any element to enable scroll animations.
 * Elements start hidden and animate in when they enter the viewport.
 *
 * Usage:
 *   - Add class "scroll-animate" for basic fade-in-up
 *   - Add class "scroll-fade" for simple fade
 *   - Add class "scroll-scale" for scale-in effect
 *   - Add class "scroll-slide-left" for slide from left
 *   - Add class "scroll-slide-right" for slide from right
 *   - Add data-delay="0.1" to add delay (in seconds)
 *   - Add data-stagger="true" to parent to auto-stagger children
