   - Kein hartcodierter Auto-Seed-Benutzer (`admin@mindsift.local` / `"Sandro"`) und kein automatischer `quickStart`-Login mehr beim Seitenaufruf.
   - Beim ersten Start (`0` Benutzer in der Datenbank) erkennt `GET /api/v1/auth/status` automatisch `needsSetup: true` und zeigt den **Ersteinrichtungs-Assistenten** (`POST /api/v1/auth/setup`) zum Anlegen des ersten Server-Admin-Kontos und der Instanz-Grundeinstellungen.

+- [x] **Profile-Dropdown & Vollbild-Einstellungsseiten (`App.tsx`, `UserSettingsView.tsx`, `GroupsView.tsx`, `AdminSettingsView.tsx`):**
   - Klick auf den Benutzer oben rechts öffnet ein eckiges, monochromes Dropdown-Menü:
     - **Kontoeinstellungen** (`UserSettingsView.tsx` — Vollbild-Ansicht für Profil & Passwort, Darstellung & Themes, Multi-Channel-Alarme, Private Webhooks & Daten-Export).
-    - **Administration** (`AdminSettingsView.tsx` — nur sichtbar für `admin` und `team_admin`; Vollbild-Ansicht für Benutzer, Rollen, Einladungscodes, Organisationen & Teams, Server-Isolation und SMTP-Mailserver).
+    - **Gruppen** (`GroupsView.tsx` — für alle Benutzer; Self-Service Erstellung und Verwaltung von Gruppen, Mitgliedern und Rollen).
+    - **Administration** (`AdminSettingsView.tsx` — nur sichtbar für `admin`; Vollbild-Ansicht für Benutzer, Einladungscodes, Server-Isolation und SMTP-Mailserver).
     - **Abmelden** (bereinigt JWT-Token und führt zurück zum Login-Bildschirm).
-  - 3-stufiges Rollensystem: `admin` (Server-Admin), `team_admin` (Team-Admin mit Berechtigung zum Einladen und Verwalten von Teams) und `member` (Mitglied).
+  - Klares Rollensystem: Global `admin` (Server-Admin) und `member` (Standard-Benutzer). Innerhalb von Gruppen: `admin` (Gruppen-Admin) und `member` (Gruppen-Mitglied).
   - Layout-Fix im Benutzer-Erstellungsformular (`grid-cols-1 sm:grid-cols-2 lg:grid-cols-4 gap-3` mit `min-w-0`), sodass das Rollen-Dropdown niemals über den Container hinausragt.
 - [x] **Multi-Channel-Alarme: E-Mail (SMTP), Discord & Eigener Webhook (`UserSettingsView.tsx`, `AdminSettingsView.tsx`, `server.go`):**
   - Tab heißt klar **Alarme** mit frei kombinierbaren Zielen (`alarmChannels`: `'email'`, `'discord'`, `'webhook'`).
