/* UI-REDESIGN-01A – kleines, gemeinsames EUROVIA-Designsystem.

   Isolationsregeln (bewusst):
   - KEINE Element-Selektoren auf oberster Ebene (body, h1, button, table ...).
     Elemente werden nur innerhalb eigener ev-Container angesprochen.
   - Alle Variablen tragen das Praefix --ev-, alle Klassen das Praefix ev-.
   - Bestehende Klassen (app-*, bb-*) werden ausschliesslich unterhalb der
     Seiten-Container .ev-workspace bzw. .ev-billing nachgestaltet, damit
     Belegpruefung, Abrechnungsdetails und Admin-Masken unveraendert bleiben.
   - Kein !important, keine externen Ressourcen, nur System-Fonts. */
