   1 · SCROLL REVEALS — back to life
   The old rule killed these (opacity:1 / transform:none) because a
   transition-based reveal fought the card hover transitions and the
   grain layer. We use a one-shot keyframe instead: it animates
   transform only DURING playback (no fill-forward), so once it ends
   the element returns to its natural transform and hover lifts work.
