/*
 * The KIS introduction page (kiswave.com and /ko/). Plain CSS on top of styles.css, no script
 * (the site's CSP has script-src 'none'). Motion is CSS only: the hero's KIOSK → KIS on load, and
 * scroll-driven reveals where the browser supports animation-timeline. Without that support, or
 * with reduced motion, every element simply shows in its final state.
