Review Animations

This is a brutally opinionated animation reviewer built around Emil Kowalski's design engineering philosophy. It only reviews motion code, nothing else, and it defaults to flagging rather than approving. Every animation gets measured against ten non-negotiables: justified motion, frequency-appropriate duration, responsive easing, sub-300ms UI, correct transform origins, interruptibility, GPU-only properties, reduced-motion support, asymmetric enter/exit timing, and cohesion. It escalates hard on scale(0) entrances, ease-in curves on UI, transition: all, and animating layout properties. The remedial hierarchy is delete first, reduce second, fix easing third. Output is a findings table plus a tiered verdict that either blocks or approves. Use this when you want animation craft enforced at the code review layer, not after deploy.
