/* ------------------------------------------------------------------
   Preview 8: S01 three-image crossfade, 1 > 2 > 3 > 1 ...
   Image 1 stays the .hero::before background: it shows at once and is the
   static picture without JS, with reduced motion or if a photo fails.
   Images 2 and 3 sit above it (below the green ::after overlay) in
   .hero-slides, hidden until site.v3.js has loaded them, then faded with
   opacity only. 13.5s cycle = 3 x (3s hold + 1.5s fade):
     22.2-33.3%  image 2 fades in over image 1
     55.6-66.7%  image 3 fades in over image 2
     70%         image 2 drops away, unseen under image 3
     88.9-100%   image 3 fades out, revealing image 1
   Both layers end at opacity 0, as they start, so the loop has no reset.
   The one-time hero-zoom entrance (scale on .hero::before only) is
   untouched: it ends at 2.4s, and image 2 cannot appear before the page
   has loaded plus the 3s hold, so the two animations never overlap and
   never share a property.
