# Production single-box topology. `docker compose up -d --build` brings up the full stack behind
# Caddy (auto-HTTPS). Postgres and MinIO stay on the internal network only (no host ports); the
# public surface is Caddy on 80/443. For local dev, opt into docker-compose.dev.yml explicitly
# (`-f docker-compose.yml -f docker-compose.dev.yml`); it is deliberately NOT named
# docker-compose.override.yml so its host-port/no-TLS settings never auto-merge here. See
# docs/deploy.md.

# Shared build config: pass NEXT_PUBLIC_WS_URL as a build arg so Next inlines it into the client
# bundle at build time (F29). A runtime-only env_file does NOT reach the client bundle.
