How it works: Detects links within the viewport (using Intersection Observer) Waits until the browser is idle (using requestIdleCallback) Checks if the user isn’t on a slow connection (using navigator.connection.effectiveType) or has data-saver enabled (using navigator.connection.saveData) Prefetches URLs to the links (using or XHR). Provides some control over the request priority (can switch to fetch() if supported).
