   Trockenbauservice Hannover – Designsystem 2026
   Schwestermarke von Montageservice Hannover: gleiches Papier, gleiche Tinte,
   gleiches Signalgelb. Trockenbau spricht leiser: feine, breite Archivo-Schnitte,
   Haarlinien, Millimeterraster wie auf dem Bauplan.
   Bewusst ein helles Theme (Markenauftritt).
