#   echo "ENCRYPTION_KEY=$(openssl rand -hex 32)"       >> .env

# LAN / plain-HTTP self-hosts (NAS, homelab, Tailscale): set
#   SESSION_COOKIE_SECURE=false

# and login silently fails. This is the single most common self-host snag.
# Leave it unset (or true) only when a TLS reverse proxy serves HTTPS.

# Persistent state lives in exactly one named volume (`pgdata`, Postgres'
# data dir). The app container is stateless, so a backup of the database is
# a backup of everything. The optional GeoLite2 databases are either baked
# into the image at build time or mounted read-only from the host and
# pointed at with GEOLITE2_DIR — either way they are replaceable, not state.

# Shared web/worker environment. `app` and the optional `app-worker` below
# both merge this anchor with `<<: *healthlog_env` instead of each keeping
# their own copy of the list. A hand-copied second list is exactly how the
# app-worker example drifted before: `app` grew to 62 variables over time
# while the worker example stayed at 14, missing every SMTP_*, VAPID_*,
# APNS_*, INSIGHTS_MAX_TOKENS and ALLOW_LOCAL_AI_PRIVATE_HOSTS entry — so a
# deployed worker (the process that sends notifications and runs the AI
# jobs) silently couldn't email, push, or send APNs, and had no local-AI
# host allowlist. One shared block makes that drift structurally
# impossible. HEALTHLOG_PROCESS_TYPE is the one value that's meant to
# differ per service and is overridden after the merge.
