/* rsvglobal.co: shared stylesheet for service and case pages.
 *
 * index.html deliberately keeps its own inline CSS: it is the page most likely
 * to be opened straight from disk and it carries hero treatments nothing else
 * uses. Everything below is the shared system for the pages under /services/
 * and /work/, so a change to the nav or a button lands in one place instead of
 * ten. See AGENTS.md.
