+### Admin UI
+
+**Community Inbox** (`/admin/community/inbox`):
+- Einheitliche Ansicht aller Kommentare (YouTube + Facebook + Instagram)
+- Filter nach Plattform, Status, Priorität, Sentiment, Flags
+- AI-generierte Antwort-Vorschläge (Claude)
+- Direkte Antwort-Funktion
+- Echtzeit-Updates via SSE (`/api/community/stream`)
+- Export als CSV/JSON
+- Sync-Button (triggert alle Plattformen)
+
+**Community Analytics** (`/admin/community/analytics`):
+- KPI-Cards (Gesamt, Heute, Unbeantwortet)
+- Sentiment-Trend-Chart
+- Topic-Cloud
+- Response-Metriken
+- Kanal-Vergleich
+- Top-Content nach Engagement
+
+### Meta (Facebook + Instagram) Integration
+
+**OAuth-Flow:**
+```
+1. Admin öffnet /api/auth/meta?socialAccountId=X&accountType=both
+2. Redirect zu Facebook OAuth (12 Scopes)
+3. Callback: Short-Lived → Long-Lived Token (60 Tage)
+4. Facebook Pages + Instagram Business Accounts werden geladen
+5. Token + Account-Daten in SocialAccounts gespeichert
+```
+
+**Unterstützte Scopes:**
+- Facebook: `pages_show_list`, `pages_read_engagement`, `pages_manage_posts`, `pages_read_user_content`, `pages_manage_engagement`, `pages_messaging`
+- Instagram: `instagram_basic`, `instagram_manage_comments`, `instagram_manage_messages`, `instagram_content_publish`
