 * Right-rail "On this page" navigator with scroll-spy.
 *
 * Uses IntersectionObserver to track which heading is currently in the
 * viewport's top band and highlights the matching TOC entry. Falls back
 * to the last heading above the viewport when nothing is in view so the
 * TOC never blanks at the bottom of a long page.
 *
 * rootMargin tuned to `0 0 -65% 0` — heading becomes active when it
 * enters the top 35% of the viewport. That feels natural for reading
 * speed without ping-ponging at chapter boundaries.
