/*
 * @dreamtree-org/landing-kit — the shared marketing site.
 *
 * Plain CSS on --dt-* custom properties, the same ones @dreamtree-org/auth-kit
 * uses: --dt-brand (and optionally --dt-brand-accent / --dt-brand-panel) come
 * from the `brand` prop; every other colour is derived here, so the landing
 * page and the login screen are one family. Works the same under Tailwind 3,
 * Tailwind 4 (preflight or not) or no Tailwind: every block sets its own
 * margins, list styles and button styles.
 *
 * Dark mode: [data-theme="dark"] on <html> (twreact-ui ThemeProvider), a
 * `.dark` ancestor, or data-theme="dark" on the .dt-landing element itself.
