/**
 * Open Props Scroll Animations
 * A comprehensive collection of scroll-triggered animations using Open Props design tokens
 *
 * USAGE:
 * 1. Include Open Props CSS: <link rel="stylesheet" href="https://unpkg.com/open-props"/>
 * 2. Include this file: <link rel="stylesheet" href="open-props-animations.css"/>
 * 3. Include the JS: <script src="open-props-scroll-animations.js"></script>
 * 4. Add animation classes to your HTML elements
 * 5. Optional: Add data-repeat attribute to re-animate on every scroll into view
 *
 * ANIMATION TYPES:
 * - Basic: fade-in, slide-in-*, scale-in, rotate-in, etc.
 * - Combinations: slide-fade-*, scale-rotate-*, etc.
 * - Elastic: *-elastic (bouncy entrance)
 * - Spring: *-spring (springy entrance)
 * - Special: blur-in, zoom-blur-in, flip-*, etc.
 *
 * ATTRIBUTES:
 * - data-repeat: Re-animate every time element enters viewport
 * - data-parallax="0.5": Add parallax effect (0.1=subtle, 0.5=strong)
 * - data-counter: Animate numbers counting up
