/* ==========================================================================
   MN BAU & Dienstleistung - Stylesheet
   --------------------------------------------------------------------------
   Eigenes CSS, kein Framework. Aufbau: mobile-first.
   Alle Farben, Schriftgrößen, Abstände und Rundungen stehen unter :root
   (hell) und unter ".dunkel" (dunkle Abschnitte) und werden nur dort geändert.

   Rundungen: keine. Alle Ecken sind eckig (Buttons, Felder, Karten, Fotos).

   Farben: helles Betongrau als Grund, Anthrazit für die dunklen Anker
   (Kopfbild, Einsatzgebiet, Kontakt, Fußbereich), Gold als einziger,
   sparsamer Akzent (Linien, Icons, zweite Titelzeile, Block hinter dem Foto).

   Bewegung: sanftes Einblenden, Hover-Zustände.
   Bei "Bewegung reduzieren" im System gibt es keine Animationen.
