/* Reliva motion layer - scroll-triggered reveals.
   Drop this stylesheet onto any page, then add a data-reveal attribute to elements.
   The companion motion.js watches them and adds .is-visible when they enter the viewport.

   Usage:
     <div data-reveal="fade-up">...</div>
     <div data-reveal="fade-up" data-reveal-delay="200">...</div>
     <div data-reveal="fade-in" data-reveal-delay="400">...</div>

   Variants: fade-up, fade-down, fade-in, scale-in, slide-left, slide-right.
   Honours prefers-reduced-motion. */
