/* Full-width portfolio images get a LONGER, gentler, deeper reveal than grid
   tiles — the jigsaw feel: a piece slides up and settles into place.
   Three reasons the shared timing read as a blink here:
     · there is far more of the page moving, so 0.6s is over before the eye
       has travelled with it;
     · --ease-out is heavily front-loaded (it reaches ~75% at 20% of the
       duration), so most of the fade happened in the first fraction;
     · a 32px rise is barely a seventh of these images, so it read as a fade.
   Bigger pieces travel further — that keeps the proportions in step with the
   smaller tiles rather than only scaling the duration. Tiles are left alone. */
