/*
   Not `forwards`-filled: `forwards` would permanently pin opacity/transform
   above the exit transition's own values in the cascade, breaking the
   staggered fade-out above. Using `backwards` only holds the pre-start frame
   during the delay so there's no flash back to the resting opacity:1 before
   the animation kicks in — once it finishes, control reverts cleanly to the
   normal (resting) rule below.
