+# Local development / smoke-test compose file.
+# Unlike docker-compose.example.yml (which pulls a pre-built image from a registry),
+# this file BUILDS the image from the local Dockerfile so you can iterate without
+# pushing anywhere.
+#
+# Usage:
+#   1. Copy .env.example to .env and fill in UPDATER_API_KEY (e.g. `openssl rand -hex 32`)
+#   2. Optionally adjust STACKS_ROOT below to point at a directory you actually have
+#      compose stacks in (default points at this repo dir, which is fine for smoke tests)
+#   3. docker compose -f docker-compose.local.yml up --build
+#   4. curl -s http://localhost:8080/healthz | jq
+#   5. curl -sH "Authorization: Bearer $UPDATER_API_KEY" -d '{"image":"test"}' \
+#        http://localhost:8080/update | jq
