* Node 25 and later ship their own `localStorage`, and under jsdom it shadows
* jsdom's. With no `--localstorage-file` it is an empty shell, so every web test
* that writes or reads a save fails. Turning it off hands the global back to
* jsdom. Node 22, which the repo pins, accepts the flag and changes nothing.
*
* It lives here because Vitest reads worker arguments only from the root config;
* a project cannot set its own.
