RevealGroup's whileInView fires once per component instance. Since a
category-filter navigation re-renders the same /blog page in place
(only searchParams changes, no full remount), and rest.length stays
> 0 across most filter transitions, RevealGroup itself never
naturally unmounts — so once it already fired "show" for one
filter's list, newly swapped-in RevealItems (different post ids)
mounted into an already-settled parent with no reason to re-fire the
reveal trigger, staying stuck at opacity 0 forever. Keying
RevealGroup (and the featured Reveal) on the actual rendered post
set forces a remount whenever the filtered posts change, restarting
the viewport tracking each time.
