- * and is shared across test files -- both wrong for tests). Suites that touch
- * storage therefore threw `Cannot read properties of undefined`, taking out
- * every test in the file rather than just the ones that used it.
+ * Core's vitest setup.
  *
- * A per-process in-memory implementation is enough: it satisfies the Storage
- * interface the app uses and keeps nothing on disk.
+ * The polyfills live in the SDK so core and every plugin suite share one copy.
