// genuine cross-origin CORS enforcement and the prod service worker offline
// path. We stage Origin B (CORS JSON) and Origin A (a real hub build) HERE at
// config load — before the webServer array starts — because Playwright launches
// webServers before globalSetup. The two webServer entries then serve the staged
// dirs, and the hub reads Origin B over the network like a deployed hub would.
