+## Free-Only Lockdown
+
+The asset pipeline is currently free-only. Before download or import, verify
+that the asset page is marked free or that the asset is project-owned/internal.
+Record the cost in `Docs/Art/AssetLicenses.md` as `Free`, `$0`, `0`, or `N/A`.
+
+Do not click purchase, checkout, add payment, subscription, or paid-license
+flows. If an asset looks useful but is not free, record it as a candidate in
+notes outside the import flow and wait for explicit approval.

+Until Nathan explicitly approves a paid purchase, every third-party asset must
+have `Cost` recorded as `Free`, `$0`, `0`, or `N/A` for project-owned/internal
