   SCROLL REVEAL — fail-safe
   .reveal elements are always visible by default. JS adds an
   .is-observed class right before observing them, which kicks
   in the hidden state, then .is-visible animates them back.
   This means: if JS fails OR elements never enter view OR
   playwright takes a full-page screenshot — everything is still
   visible, just not animated.
