/*
 * Cockpit public website (KAN-336, docs/website.md kap. 5): tokens, layout and components.
 * Tokens mirror packages/ui/src/theme/tokens.css (--ck-*): same surfaces, text, accent and status
 * colours, same fonts. The site follows the OS theme (prefers-color-scheme); [data-theme] on <html>
 * forces one. The app mock in the hero always uses the app's default dark theme, like a screenshot.
 *
 * Fonts are self-hosted (no request to a third party): Inter and JetBrains Mono, both under the
 * SIL Open Font License 1.1 (fonts/OFL-Inter.txt, fonts/OFL-JetBrainsMono.txt), variable weight,
 * latin and latin-ext subsets from the @fontsource-variable packages 5.3.0.
