This masterfully choreographed full-page slider captures wheel, swipe, and key events to drive a multi-layered transition. Utilizing GSAP Observer, the layout animates parent and child containers in opposite directions, producing a clean split-wipe reveal. Simultaneously, a custom variable font dynamically stretches its width axis (wdth) alongside parallax image transformations to create an organic, tactile sense of momentum.
