/**
 * playwright.config.ts
 *
 * E2E tests in `tests/e2e/` run against a real built app (`npm run test:e2e`).
 * They cover the handful of behaviours that only reproduce in a browser -
 * hydration timing, autofill, WebAuthn ceremonies - which the Node-environment
 * unit suite and the Postgres integration suite structurally cannot reach.
 *
 * `webServer` builds and boots the app itself, reusing one that's already
 * listening outside CI. Specs must not depend on seeded accounts or leave
 * state behind; anything that needs a database belongs in the integration
 * suite instead.
