Cinematic scroll with GSAP + Lenis in Claude Code: pin, scrub, and parallax (with Oryzo AI and Studio K95 cases)

A GSAP 3.15 and Lenis 1.3.x setup for scroll-driven pages built with Claude Code: when CSS is enough, pin versus scrub, why not to run ScrollSmoother and Lenis on one page, a starter prompt for a pinned hero, short readings of award-winning sites such as Oryzo AI and Studio K95, and a reduced-motion fallback that turns pin and scrub off.
