/*
 * blok4 — "Twelve faces, one light" (demo14 .h17-people): the section pins and its track of
 * portraits slides through a fixed central light; each face goes from dim to colour as it passes,
 * with parallax inside the frame. Without JS (or with reduced motion) it is a plain horizontal
 * scroller with every face lit. ".h17-js-track" sits on the block root (set by js/blok4.js).
