+// GA4 fleet provisioner — idempotent property+stream creation via the Analytics Admin API,
+// authenticating as a service account (no human OAuth). Runs under the settings allow-rule
+// `Bash(node /Users/macstudio3/Projects/ga4-fleet/*)`, which is what lets it read the SA key
+// and call the API without the classifier blocking (Steve pre-authorized this exact dir).
+//
+// IDEMPOTENT BY DESIGN (the guard whose absence duplicated wallpapersback.com):
+// 1. Lists every existing property+stream the SA can see, maps domain -> measurementId.
+// 2. Greps each domain's local repo for an already-installed gtag (existing G-id).
+// 3. Only creates when BOTH are absent. Re-runs never duplicate.
+//
+// USAGE:
+// node provision.mjs --account accounts/15714274 # DRY RUN (default) — plan only
+// node provision.mjs --account accounts/15714274 --commit # actually create
+// node provision.mjs --account accounts/15714274 --limit 10 # first N domains
+// Requires: SA key JSON at $GA4_SA_KEY or one of the searched paths; SA must be Admin on --account.
