/* =====================================================================
   Kerala — God's Own Country. Photo scroll experience.
   Two modes:
     • default (no JS / reduced-motion): scenes stack vertically, readable.
     • html.is-animated: scenes become a fixed full-screen stage; GSAP
       cross-fades them and Ken-Burns / parallaxes the photos on scroll.
