## Monitoring stack — Loki + Grafana
## Usage: docker compose -f docker-compose.yml -f docker-compose.monitoring.yml up -d
##
## Grafana: http://localhost:3003 (admin/admin on first login)
## Loki: http://localhost:3100 (internal, used by Grafana)
##
## The app sends logs to Loki via HTTP at http://loki:3100/loki/api/v1/push
