/* ==================================================================
   Celebi Reinigung – Stylesheet, Version 2
   ------------------------------------------------------------------
   Die Farben stehen als CSS-Variablen in functions.php
   (Funktion celebi_color_vars). Dort ändern, nicht hier.

   Gestaltungsidee
   Ruhig und handwerklich statt verspielt. Viel Weißraum, feine
   Trennlinien statt Schatten und Kärtchen, echte Fotos mit
   Bildunterschrift. Markenblau nur dort, wo gehandelt wird:
   Buttons, Links, Kontaktbereich.

   Aufbau
   01  Grundlagen
   02  Layout und Typografie
   03  Buttons und Links
   04  Kopfzeile und Menü
   05  Hero
   06  Leistungen
   07  Ablauf
   08  Warum wir und Fotos
   09  Kontakt und Formular
   10  Fußbereich
   11  Mobile Aktionsleiste
   12  Textseiten und Hinweise
   13  Bewegung
   14  Responsive
