/**
 * DPP Enterprise Light Architecture — theme.css
 * 
 * Höchste Schweizer Design-Präzision für Industrie, Markenhersteller & B2B-Unternehmen.
 * Inspiriert von Stripe, Apple Environmental Reports, Circularise und Porsche Digital.
 * 
 * Prinzipien:
 * - 100 % seriöses, klares Light-Design (Kein Crypto/Gamer-Dunkelmodus)
 * - Pure White & Paper-Grey Oberflächen mit mikroskopisch feinen Konturen
 * - Perfekte Lesbarkeit, ruhige Kontraste und vertrauenswürdige Farbgebung
 * - Dynamisches White-Labeling (Jede Corporate Identity fügt sich nahtlos ein)
