/* ---------------------------------------------------------------- pinned scrollytelling */
/* The visual sticks via native `position: sticky` (not a GSAP pin) — that
   avoids the classic trap of pinning inside a `align-items: center` grid row
   whose height is fought over by `min-height: 100svh` vs. the steps' own
   content height, which either strands the pin off-screen or leaves almost
   no scroll runway when step copy is short. Sticky just tracks the column
   naturally. Each step also gets deliberate scroll-pacing height on desktop
   so the layer swap has room to read as a transition, not a flicker. */
