// E2E hub harness for the frontend's Playwright suite (frontend/e2e). Not
// part of the normal test suite: it only runs with BDRIVE_E2E_SERVE=1, where
// it serves a small deterministic hub on :8993 until killed. Playwright
// starts it via its webServer config and tears it down after the run.
//
// Unlike the manual demo harness, state is wiped on every start so the
// tests always see the same world: one org ("default", owned by the admin
// account), one project ("wiki") with a handful of seeded files, two
// accounts, one share-ready markdown tree with wikilinks, and enough read
// heat to light up the insights views.
