Motion as feedback, not decoration

Motion earns its place when it answers a question: which card is active, where did the nav pill go, is the site still loading? Everything else is a candidate for removal.

Reduced motion is not an afterthought. Autoplay, intro curtains, and parallax all respect prefers-reduced-motion, and scroll-driven stage interactions still work with static fallbacks.

GSAP handles the heavy choreography — deck spins, split-curtain intros, magnetic buttons — but the system defaults stay in CSS so the site remains usable when JavaScript is slow or absent.
