/*
 * Section components for the public site.
 *
 * The vocabulary the long-scroll homepage and the News / Masala / Search
 * pages are built from: section headers with a gold rule, icon tiles,
 * media cards, a statistics band, the alumni band and the tabbed
 * introduction card. Every colour is a palette token from theme.css, so
 * these read correctly for any institution's palette.
 *
 * Motion belongs to motion.css - a component here never animates itself,
 * it just carries `motion-lift` / `data-reveal` where that is wanted.
