+Add `"files": ["dist"]` to both app and backend packages. This ensures that packaged versions of these packages do not contain unnecessary files.
+
+To apply this change to an existing app, add the following to `packages/app/package.json` and `packages/backend/package.json`:
+
+```json
+  "files": [
+    "dist"
+  ]
