/*
 * Shared stylesheet for the static Berglabs pages (kontakt, företaget,
 * integritetspolicy, användarvillkor). Mirrors the design tokens and visual
 * language of the React-built homepage (src/styles.css + shadcn/ui) so the
 * whole site feels like one product, without depending on the Tailwind
 * build pipeline (Tailwind only scans src/, not public/).
 *
 * Direction: spacious, quiet, confident — generous whitespace, big Manrope
 * headlines, no boxed/bordered cards, navy (#102866) reserved for one clear
 * accent per page rather than spread across every element.
