Blue-green zero-downtime deploys, promote flow validation. Dual auth: local (bcrypt + JWT) and OAuth2/OIDC (any provider). Auth middleware, login page, auth settings UI. Structured logging (slog JSON), config export to YAML. Graceful shutdown with deploy draining. Multi-stage Dockerfile and production docker-compose.yml. Swap phase order: Volumes & Env before UI Polish.
