/**
 * Vitest global setup.
 *
 * Node ≥ 22 defines a `localStorage` accessor on globalThis that resolves to
 * `undefined` unless the process was started with `--localstorage-file`
 * ("localStorage is not available because --localstorage-file was not
 * provided"). Because that key already exists, the jsdom environment's
 * global population never installs the document's own store, so a test
 * calling the bare global `localStorage` throws "Cannot read properties of
 * undefined" even though jsdom has a working one.
 *
 * Bridge the two: point the global at the jsdom window's Storage. The jsdom
 * environment exposes its instance as `globalThis.jsdom`; node-only suites
 * (no jsdom global) keep Node's accessor untouched.
