# In production the browser talks to Caddy on :80/:443.
# Caddy proxies /api/* and /health straight to backend, the rest to frontend.
# So the frontend uses same-origin relative URLs — no NEXT_PUBLIC_API_BASE_URL needed.
#
# Postgres + Redis run alongside the app on the same VM (Discovery mode).
# Volumes are shared with docker-compose.yml so switching between files preserves data.
