/*
  NEURAL DESIGN SYSTEM — monolithisches CSS fuer den gesamten Gemini-/REPLIT-PUSH-Stack.
  Ein File, ueberall injiziert (<link rel="stylesheet" href="/shared/css/neural.css">).

  Herkunft: passend zur bestehenden Genitus-Inc.-Markenwelt (genitus.org, celestiaos.com,
  globalfintech.net) -- dunkles Navy/Schwarz, Cyan-Glow-Akzente, Orbitron fuer Marke/
  Ueberschriften, Inter fuer Fliesstext. Zusaetzlich ein Gold-Akzent-Preset fuer
  Fintech-Tools (siehe GlobalFintech/GoldShield-Branding).

  Struktur dieser Datei:
    1. Tokens (Light + Dark via prefers-color-scheme + data-theme-Override, Gold-Preset)
    2. Reset + Basis-Typografie
    3. Barrierefreiheit (Fokus, prefers-reduced-motion, Skip-Link, sr-only)
    4. Layout: App-Shell, Navbar mit Hamburger/Mobile-Drawer
    5. Komponenten: Buttons, Cards, Inputs, Badges, Chat (Bubble/Input-Bar), Daten-Kacheln,
       Tabellen, Modal, Toast, Spinner
    6. Utilities: Flex/Grid/Spacing/Text
    7. Ambient-Hintergrund (optionales Neural-Node-Canvas, dezent, respektiert reduced-motion)

  Einbindung + Verhalten (Theme-Toggle, Hamburger, Ambient-Canvas): siehe neural.js.
