/* ═══════════════════════════════════════════════════════════
   SHELL — App-Shell, Sidebar, Topbar, Bottom-Nav
   GeniusHub v21 — Redesign

   Neue Struktur:
   - Desktop: #app = CSS-Grid mit .sidebar links + .main rechts
   - Mobile: Sidebar versteckt, Bottom-Nav fix unten
   - Topbar: ruhig, solide, kein Gradient

   Läuft PARALLEL zu layout.css. Styles hier haben Vorrang
   durch Reihenfolge der <link>-Tags in index.html.
