# Copy to terraform.tfvars and fill in real credentials.
#   cp terraform.tfvars.example terraform.tfvars
# terraform.tfvars is gitignored (repo_url may carry a credential, and om_rclone_conf
# always does — both land in local state). NEVER commit real values.

# App secrets (POSTGRES_PASSWORD, THERMOGRAPH_AUTH_SECRET, VAPID keys,
# REGISTRY_TOKEN, Discord/SMTP creds, ...) are NOT here anymore -- they live in
# the SOPS+age vault (../deploy/secrets/*.yaml), rendered at deploy time. See
# deploy/secrets/README.md to rotate or add one.

# Two VPS boxes, keyed by HOST (vps1, vps2) — NOT by environment, because vps2
# alone carries two (prod AND beta). Each host lists its SSH identity once, then
# an `environments` map for whatever runs on it. (The `dev` branch deploys to
# vps1 the same way in reality, but the LAN-laptop `make dev-up` rehearsal is NOT
# managed by Terraform at all.)
