  /* iOS Safari renders background-attachment:fixed as a blurry/pixelated
     mess on real devices (a long-standing engine bug), even though it looks
     fine in a desktop browser engine — so mobile can't use real fixed
     attachment. A CSS-only position:sticky + negative-margin stand-in was
     tried, but its "unstick" boundary didn't reliably line up with the
     wrapper's actual bottom edge, so the background bled into the next
     section. Real position:fixed on an actual element doesn't have iOS's
     background-attachment bug, so script.js drives .merge-bg by hand
     instead: position:fixed (full viewport, like a true fixed background)
     while its wrapper is on screen, then position:absolute pinned to the
     wrapper's own top/bottom edge once scrolled past — so it can never
     bleed into a sibling section. overflow:hidden on each wrapper is a
     second line of defense: it clips the absolute-pinned state to the
     wrapper's own bounds (position:fixed always escapes it, by design). */

  /* .process__bg combined its two gradient layers with the photo itself,
     using background-attachment:fixed,fixed,fixed. That has the same iOS
     blur bug as everywhere else, and even with plain scroll attachment, the
     photo layer sized to .process's own (fairly tall, multi-item) box would
     cover-crop to whatever slice of the image happens to fall in that
     range — which is what showed up as a jarring color band on real
     devices. Same fix as the merge wrappers: drop the photo from
     .process__bg (keep just the two gradients, which are vector and never
     have a crop/zoom problem) and let the script-driven .merge-bg above
     handle the photo, sized against the viewport instead. */
