/*
 * digiloom: history timeline.
 * Source: Figma Make `History.tsx`. Framer Motion drove the rail fill from
 * scroll progress through the container; here the fill height is a custom
 * property set by js/digiloom-motion.js. With no JS the rail reads as fully
 * drawn, so no milestone is ever hidden.
 *
 * Layout: single left-rail column on small screens; from 782px the cards
 * alternate either side of a centre rail.
