/* ==========================================================================
   Rohrreinigung Naumburg (Hessen) — "Leitungsschnitt"
   Visuelles Konzept: Die Seite folgt dem Weg des Abwassers von oben nach
   unten – Sanitärobjekt → Rohrleitung → Kanal. Technische Linienführung
   (Rohrstrecke mit Knoten), Blueprint-Raster im Hero, harte Hell/Dunkel-
   Wechsel, ein kohärenter Outline-Icon-Satz.
   Marken-Tokens ausschließlich aus global.css (--primary, --c-dark, …).
   Keine neuen Farben, keine neuen Schriften, kein Framework.
