## Description

ScrollReveal is a JavaScript library designed to manage scroll-triggered visual transitions for web elements. It functions as a framework for tracking element visibility relative to the browser viewport, allowing developers to apply declarative animation sequences as users scroll through a page.

The library provides centralized control over motion design by maintaining a global configuration registry that merges with local element settings to ensure consistent behavior. It distinguishes itself through its lifecycle management capabilities, which include the ability to stagger the reveal of multiple elements using timed intervals and a mechanism to revert elements to their original state by removing styles and event listeners.

Beyond basic triggering, the project handles the entire lifecycle of an animation, including pre-render visibility suppression to prevent content flashes during page loading. It utilizes class-based state management to toggle elements between hidden and revealed states, ensuring that motion patterns remain organized and predictable throughout a user session.
