/**
 * FLOWNIQ Demo-Flow CTA Modal & Form Styles (alternativer CTA)
 *
 * Self-contained stylesheet for the Demo-Flow modal (PDF-Upload + Prozessbeschreibung).
 * Vollständig unabhängig vom Standard-CTA. Auf einer Seite wird genau eines der
 * beiden CSS-Files eingebunden:
 *   Standard:   <link rel="stylesheet" href="/css/flowniq-cta.css">
 *   Demo-Flow:  <link rel="stylesheet" href="/css/flowniq-demo-cta.css">
 *
 * Die Basis-Modal-Regeln sind bewusst identisch zu flowniq-cta.css gehalten,
 * damit beide CTAs gleich aussehen. Demo-spezifische Elemente (Dropzone,
 * Textarea, "und/oder"-Trenner) sind klar markiert.
