   1860 motion layer
   Shared animations for the public site: promo popup enter/exit, scroll
   reveal, card hover lift and button press feedback. Everything that hides
   content (reveal) is opt-in via classes that 1860-motion.js adds, so with
   JS off nothing is ever left invisible. All of it is switched off for
   visitors who ask for reduced motion.
