Overlap collection with page load

The fastest way to ship fingerprinting without adding perceived latency is to start collection the moment your script executes. Use createCollector, call start() at the top of your page-load handler, and await getResult() only when you actually need the value — for example, on form submit or before an API call.

In a typical single-page app, by the time the user has interacted with the first screen, the 1.2–1.6 s collection window has already passed and getResult() returns immediately.
