/* Design-System "Petrol · Volt · Kupfer" v2.1 (H:\design-system-econsult.md),
   projektübergreifendes Update für die Econsult-Familie (siehe elt-planung-suite).
   Bootstrap bleibt Basis für Formulare/Tabellen/Modals; wir tönen die
   vorhandenen Bootstrap-Komponenten über deren eigene --bs-btn-*-Variablen
   um (globals.css lädt nach bootstrap.min.css, gleiche Spezifität gewinnt
   per Ladereihenfolge) statt Bootstrap zu ersetzen.

   Dark mode: Bootstrap schaltet seine eigenen Komponenten (Formulare,
   Modals, Cards, Alerts, ...) automatisch um, sobald `data-bs-theme="dark"`
   auf <html> steht (gesetzt von ThemeToggle.tsx, persistiert in
   localStorage). Der custom Stromkreis-Grid nutzt dafür dieselben
   Tokens unten, per `:root[data-bs-theme="dark"]` überschrieben. */
