- one gate (motionEnabled): off under reduced-motion, missing matchMedia, and vitest; every path checks it first - mount/filter-change only: count-up and bar grow-in key off the period|provider|range key, so 30s poll refreshes snap values silently instead of re-animating - first-load skeleton shimmer replaces bare scanning text (kept sr-only for screen readers); slide-in toast host for Settings/export feedback (validation errors stay inline); CSS hover-lift + press micro- interactions, all with a reduced-motion escape hatch - gsap 3.15.0 + @gsap/react 2.1.2 (+74KB raw JS; G4 flame work shares it) 244/244, typecheck + build green.
