+# Intended for: Fly.io / Railway / Render (or any platform that provides PORT).
+# - Binds the gateway on all interfaces (required for container/PaaS routing).
+# - Relies on `${ENV_VAR}` expansion so secrets stay in platform env vars.
+#
+# For a full example with more options, see: config/default.yaml
