+# Prod-shaped template — mirrors the live `7cav-api` stack.

+# Prerequisites for `docker compose up`:
+#   - A `xenforo` stack is already running (provides `xenforo-db` on
+#     the `xenforo_internal` network).
+#   - The external networks exist:
+#       docker network create edge
+#       docker network create xenforo_internal
