- backend-net (internal: true): db ↔ backend ↔ frontend reverse proxy
- frontend-net: frontend only; single host port binding (80 prod / 5173 dev)
- Remove ports: from db (5432) and backend (8000) — unreachable from host
- Security auditor: hard rule to never add host ports to db or backend

- frontend prod: USER root for adduser, then USER appuser (1001:1001); fixes
build failure caused by nginx-unprivileged already setting USER nginx
- docker-compose: frontend user updated to 1001:1001 (was 101:101)
- CLAUDE.md: add infrastructure change protocol (update README + test both
stacks after any Dockerfile/compose/nginx change); fix stale passlib ref
- README: container table shows nginx-unprivileged image, UID column, internal
port 8080 note; Current State notes all containers run as non-root
Both dev and prod stacks tested and verified (health, login, /users/me,
frontend serving, all containers confirmed non-root via docker inspect).

- 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
