- backend: appuser UID/GID 1001 via useradd, USER directive, --chown on COPY
- frontend builder: appuser UID/GID 1001 via adduser, USER directive
- frontend prod: switch to nginxinc/nginx-unprivileged:alpine (nginx UID 101), listen on 8080
- docker-compose: explicit user: for all services (70:70 db, 1001:1001 backend/frontend-dev, 101:101 frontend-prod)
- nginx.conf: listen 8080 to match unprivileged image
