/* SCANORY MOONLIT — V5 CREATIVE PROTOTYPE
   One motion language for every scene:
   press     140ms  --ease-press   the object gives under the finger
   object    900–1300ms --ease-lift (lifting, turning) / --ease-settle (arriving, landing)
   light     1600–3600ms --ease-light  light and colour never move faster than objects
   Every closed or hidden state is scoped to html.ready, so without JavaScript the
   page shows its finished state: letter open, photo developed, note and back visible. */
