Cookbook patterns

Six runnable .cookbook.ts files covering the patterns every real Playwright suite needs.

Network mocking

Route interception, response mocking, request inspection, HAR replay. Test error states without a real backend.

Authentication patterns

storageState, worker-scoped login, multi-user contexts. Skip the UI login on every test — 3-5× faster suites.
