   NoteFlow Atelier — Microinteractions Layer  v1.0
   Adds premium interaction polish on top of base styles.
   All animations respect the app's motionIntensity system
   and the browser's prefers-reduced-motion preference.

   Motion language:
     Durations: 80ms press · 150ms fast · 220ms base
     Easing: cubic-bezier(0.22, 1, 0.36, 1) — smooth deceleration
     Scale: 0.97 press · 1.01–1.02 hover lift
     Prefer opacity + transform over layout-affecting props
