  /* ---- Themenfarben (Icon-Orientierungssystem) ---------------------------
     Dasselbe Prinzip wie im Schwesterprojekt Folienkonfigurator (siehe
     dortige main.css): jeder inhaltliche Bereich bekommt eine eigene feste
     Farbfamilie, damit Icon + Farbe sofort erkennen lassen, worum es geht -
     hier an den dunklen "Leuchtreklame"-Grund angepasst (kräftige, klare
     Leuchttöne statt gedeckter Erdtöne):
       - primary/accent (Amber) - EIN Ton für "ausgewählt" UND für Preise/Geld
         (Gold = Wert - passt inhaltlich und ist zugleich die Kernfarbe der
         Marke "Leuchtbuchstabe", braucht daher keinen eigenen Preis-Ton)
       - font   (Zyan)   - Schriftart/Text
       - shape  (Violett) - Profiltyp/Bauform/Größe
       - light  (Rosé)   - Beleuchtungsart (bewusst NICHT amber/gelb, sonst
                            nicht von "ausgewählt" unterscheidbar)
       - addon  (Mint)   - Montage-Zubehör
       - admin  (Schiefergrau, hell) - Adminbereich-Systemfunktionen */
