# Production stack — Django backend + Next.js frontend + Caddy reverse proxy.
#
# Database: external (Neon, Supabase, Aiven, etc.) — set DATABASE_URL in .env.
# If you prefer a local Postgres container, add a `db:` service back and point
# DATABASE_URL at it.
#
# Quick start on a fresh Ubuntu host:
#
#   git clone https://github.com/codewithmuh/hearthline.git
#   cd hearthline
#   cp .env.example .env       # fill in DJANGO_SECRET_KEY, ANTHROPIC_API_KEY, etc.
#   docker compose -f docker-compose.prod.yml up -d --build
#
# DNS:
#   API_DOMAIN  (api.example.com)        →  this host's public IP   (Caddy → backend)
#   APP_DOMAIN  (app.example.com)        →  this host's public IP   (Caddy → frontend)
# Caddy auto-issues Let's Encrypt certs once both records resolve.
