   Brand-Tokens: Welle 1 bleibt monochrom (Starter-Defaults greifen). Sobald
   Logo + Farben vom Trainer da sind, hier --brand-* setzen. Siehe Layer 07.

   Projekt-Komponenten: trainer-teaser, testimonials, news-teaser sind
   projekt-spezifisch und leben in dieser Datei (nicht im Starter-
   components.css), damit der Starter sauber bleibt.
