feat(ui): Dark-Glassmorphism-Designsystem und Grundlayout
Optischer Rahmen der Anwendung: - Hintergrund aus drei langsam driftenden Nebeln, feinem Raster und einer Rauschtextur gegen Farbbanding - .glass / .glass-soft als Grundflaechen, .card-glow fuer den Hover-Effekt mit Farbverlaufsrand je Projektakzent - Buttons, Formularfelder und Scrollbars im gleichen Stil - prefers-reduced-motion schaltet saemtliche Animationen ab Dazu Kopfzeile mit aktiver Navigationsmarkierung, ein wiederverwendbarer Modal-Dialog (Escape schliesst, Scroll wird gesperrt), das SVG-Icon sowie Fehler- und 404-Seiten. Die Fehlerseite erkennt Datenbankprobleme und nennt direkt die drei Befehle, die in dem Fall meistens helfen. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
