+# Teardown script for the three "always-on" (cost-incurring) POC resources:
+#   1. Cloud Composer 2 environment  (GKE + Airflow, runs 24/7 — most expensive)
+#   2. Vertex AI Feature Store        (Bigtable-backed online store, billed per node-hour)
+#   3. Artifact Registry repository   (Docker images — cheap, but deleting frees storage)
+#
+# Mirrors the create scripts:
+#   setup_composer.sh, setup_feature_store.sh, setup_artifact_registry.sh
+#
+# All three can be recreated later from those scripts (see Readme / notes at bottom).
+# BigQuery datasets, GCS buckets, Pub/Sub topics and the kfp-mlops@ service account
+# are intentionally NOT touched — the setup scripts depend on them.
+#
+# Usage:
+#   ./scripts/destroy_resources.sh                     # destroy all three (asks to confirm)
+#   ./scripts/destroy_resources.sh --yes               # skip the confirmation prompt
+#   ./scripts/destroy_resources.sh --skip-composer     # leave Composer alone
+#   ./scripts/destroy_resources.sh --skip-feature-store
+#   ./scripts/destroy_resources.sh --skip-artifact-registry
+#   ./scripts/destroy_resources.sh --keep-bucket       # keep the leftover Composer DAGs bucket
+#   ./scripts/destroy_resources.sh --dry-run           # print the delete commands, run nothing
