/* ============================================================================
   SupportFlowAI — Marketing-/Info-Website (wwwroot/*.html)
   Eigenständiges Stylesheet, unabhängig von app.css (das echte Anwendungs-UI
   mit seinen zehn wählbaren Admin-Themes). Eigene Design-Sprache: ruhige,
   "weiche" SaaS-Optik mit Glow-Schatten statt harter Offset-Schatten, Cyan/
   Koralle als Markenfarben (Wasser-/Flow-Metapher zu "SupportFlow"), reine
   Sans-Serif-Typografie (kein Serif-Header-Look). Strukturell an der
   TeamPilotAI-Marketingseite orientiert (gleiche Bausteine: Hero, Kernvorteile,
   Ablaufschritte, Feature-Kacheln, CTA, Rechts-/Doku-Seiten), visuell bewusst
   eigenständig.
