     - 7..9s  fade out (overlaps NEXT photo's 0..2s fade-in, since

   Photo 2 and 3 offset by 7s and 14s. With a 9s active window and
   a 7s stride, adjacent photos overlap by 2s during the crossfade.
   Keyframe percentages (of 21s):
     0%     opacity 0   (start of fade-in)
     9.52%  opacity 1   (2s / 21s — fade-in complete)
