 ### Added
 
+- New `usage_caps_input` view-extension slot on the project settings page
+  (`/projects/:project_id/settings`). Same pattern as the existing
+  `concurrency_input` slot: downstream apps register a component via
+  `metadata: %{usage_caps_input: SomeComponent}` on the settings route and
+  Lightning renders it in the settings view. No-op for OSS Lightning by default.
