Scrolls the page from top to bottom in N steps, then back to top, waiting
a short settle period at each step. Triggers IntersectionObserver-based
lazy-loaded media and primes scroll-reveal animations so a subsequent
fullPage screenshot captures real content rather than skeleton placeholders.
Has no effect on true scroll-progress-driven parallax (those evaluate at
scroll=0 once we return to top); a stitched-capture mode is the right tool
for that case.
