   Typography — system font policy:
     The brandbook calls out Monsal Gothic (print) and Proxima Nova (web),
     both paid faces. To keep these specimens portable across Windows,
     macOS, Linux and PowerPoint WITHOUT requiring font installs, both
     display and body roles default to **Segoe UI** — the Windows system
     UI font (vorinstalliert seit Vista). On macOS / iOS the stack falls
     back via system-ui to SF Pro; on Android to Roboto.
