Move your cursor and scroll. Every layer drifts at its own depth, the haze softens the distance, and the title slips behind the cliffs as you descend.
That is the signature of the layered-parallax pattern: the giant wordmark sits between the sky and the nearest silhouette, so it disappears behind the foreground as you scroll. Atmospheric perspective (distant islands hazier and warmer, near cliffs near-black) is what sells the depth. Same engine, ~30 lines of vanilla JS, no library — pastes straight into a GoHighLevel custom-code element.
