   IMAGE FADE-IN — every below-the-fold <img> gets this class (see
   class-styles/studio-features/home-events render.php). initImageFade()
   in page-home.js adds .is-loaded once the image has actually finished
   downloading (or immediately, if it was already cached/complete), so a
   lazy-loaded image never snaps into an .rv card's scroll-reveal — it
   fades in on its own the moment it's ready, whether that's before or
   after the reveal animation already ran. The hero slideshow has its own
   version of this (.splash-img.is-active.is-loaded, in the SPLASH section
   below) since it's gated on the active slide, not just on load.
