Restructure the page so the first 4 viewports of scroll drive a Three.js scene composited on top of the Antananarivo parachute video. What's there: - Three.js (ESM, r158 via importmap) renders a low-poly cargo airliner built from primitives: cylinder fuselage, cone nose, sphere cockpit (dark glass + emissive), box wings/tail/fin, cylinder engines with torus intakes, gold trim band, navy fin with gold logo box. No external model file. - Hemisphere + directional + ambient lights tuned for golden-hour fill. - 14 cloud spheres scattered around the plane, slowly rotating. - GSAP + ScrollTrigger drive a single progress value scrubbed against scroll position. Inside the rAF loop, the camera arcs from rear-left (-0.6 rad) to front-right (+1.1 rad), radius dipping mid-flight, and the plane rolls slightly with scroll. - Three act labels (Paris CDG / Vol cargo / Antananarivo) cross-fade at 20%/40%-60%/72% scroll positions via a chained gsap timeline. - Gold CTA button stays opacity:0 + pointer-events:none until the last ~10% of scroll, then fades and scales in. Hover transform rebuilt without the old mouse-parallax tilt (fights the scroll animation). - Scroll hint pill (chevron + "Faites défiler") at the bottom of the first viewport, fades out on first scroll event. - prefers-reduced-motion shortcut: scroll stage hidden, CTA visible, no animation. Page reverts to a static screen with the video bg. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
