# =============================================================
# MPM – Management-Container
# Ein einzelner Container, der als unprivilegierter Benutzer
# folgende Prozesse verwaltet (via Supervisor):
#   - Nginx (Reverse Proxy, Port 8080)
#   - NestJS Management-Backend (127.0.0.1:3000)
# Ab Phase 3 laufen hier zusätzlich die Modul-Prozesse.
# Kein Docker-in-Docker, kein Docker-Socket.
