/*
 * Nostalgia — home merge (scroll-linked statement → image)
 * Base layout is a simple readable stack. When JS is active it adds
 * .home-merge--scrub: the section grows tall, the inner pins, and a scroll
 * progress (--merge-p 0→1) drives the text DOWN and the image UP so they meet
 * and overlap — fully reversible as you scroll back up.
