/* ============================================================
   Lumetric Studio — gemeinsames Stylesheet

   Zwei Themen, eine Designsprache:
     .thema-dunkel   Startseite und Media Agency — die Markenidentität
     .thema-metall   Mobile Studio — mattes Grau, technischer

   Struktur, Abstände, Typografie und Verhalten sind identisch.
   Nur die Farbwerte unterscheiden sich. So bleibt erkennbar,
   dass beide Bereiche zur selben Marke gehören.
