/* ==========================================================================
   Aringer IT-Service — Template-Stylesheet
   Konzept: Schaltplan / Signalpfad — passend zum IT-/Netzwerk-Hintergrund
   des Betreibers. Ruhige Basis (Ink/Paper), ein Akzent (Amber = Status-LED),
   monospaced Labels wie auf einem Gerätetypenschild.
   Schriften: selbst gehostet (IBM Plex, Space Grotesk) — keine externen
   Anfragen an Google-Server, dadurch schneller und datenschutzfreundlicher.
