+## Stack
+- Next.js
+- TypeScript
+- App Router
+- Tailwind CSS
+- Forgejo
+- Coolify
+- Supabase-ready
+
+## Struktur
+- `src/app/[locale]` – öffentliche zweisprachige Oberfläche
+- `src/app/[locale]/mitglied` – Mitgliederbereich
+- `src/app/[locale]/cms` – Moderator/Admin-Backoffice
+- `src/app/api/health` – einfacher Healthcheck
+- `src/lib/i18n.ts` – Locales und Copy
+- `src/lib/roles.ts` – Rollen-Grundlage
+- `src/lib/supabase/browser.ts` – Browser-Client-Basis
+
+## Nächste Schritte
+1. Supabase-Projekt anlegen
+2. Auth- und Rollenmodell aufsetzen
+3. Public / Mitglied / Moderator / Admin serverseitig absichern
+4. CMS- und Erlebnisarchitektur ausbauen
