/* 
   Smooth scroll-reveal animations (AOS).
   AOS applies opacity:0 + translateY to [data-aos] elements and
   animates them to visible (opacity:1, transform:none) via the
   .aos-animate class once they enter the viewport. We keep AOS's
   defaults so sections/cards smoothly rise from bottom to top while
   scrolling.

   Robustness: if the AOS JS/CDN fails to load, elements would remain
   at opacity:0 (invisible). The small guard script in footer.php adds
   the class `nii-aos-fallback` to <html> only when AOS is confirmed
   unavailable, forcing every reveal target permanently visible so
   content NEVER disappears and no blank gaps appear. By default this
   fallback is inactive and the real animations run.
*/

    opacity: 1 !important;

   content visible immediately without any reveal motion. */
