   ---------------------------------------------------------
   ZIEL:
   - Galerie-Seite optisch passend zur Startseite
   - Reiter oben sollen farblich genauso wirken
   - Home = leicht blau
   - Galerie = leicht türkis
   - Kontakt = türkis / blau
   - Über mich = warm / orange
   - Galerie bleibt eigene Seite mit eigener Grid-Optik
   - Lightbox-Bilder sollen NICHT blau wirken
