1/**
2 * DOMContentLoaded Event Deferral Helper
3 * 
4 * Intercepts DOMContentLoaded event listeners and automatically wraps their
5 * callbacks with requestAnimationFrame to prevent forced synchronous layouts
6 * (reflows) that negatively impact page performance metrics.
7 * 
8 * This approach maintains full backward compatibility while deferring layout-
9 * triggering operations (offsetHeight, getComputedStyle, etc.) until the next
10 * animation frame, allowing the browser to optimize rendering.
11 * 
12 * @see https://web.dev/avoid-large-complex-layouts-and-layout-thrashing/
