   from and before the IntersectionObserver logic in footer.php.

   This matters: if this were unconditional (".reveal { opacity:0 }" with
   no gating class), any failure in the JS — blocked script, caching
   issue serving stale/broken JS, a conflict with another plugin's script
   erroring out first — would leave every section using .reveal PERMANENTLY
   invisible, with no fallback. That's a fail-*unsafe* default: broken JS
   silently deletes real content instead of just skipping an animation.
   Gating behind a class that only JS can add makes the failure mode
   "content shows immediately, no animation" instead of "content vanishes."
