   intrinsic size, which is indeterminate here — classic CSS grid "blowout"
   that made the column resolve to a many-million-pixel width and pushed the
   image off-screen. This must be pinned at EVERY breakpoint, including the
   single-column mobile layout below `lg:` — an implicit default track has the
   exact same unconstrained behavior as a bare `1fr` one. */

   surprises from a JS-driven pin), while GSAP ScrollTrigger only measures
   scroll progress across the wrap and reports it back to the frame renderer. */
