// ============================================================
// SHARED PLAYWRIGHT FIXTURES
// ============================================================
// Provides:
//   - `test` — augmented @playwright/test with auto-applied uncaught-error
//     guards on every page (pageerror + console.error → test fail)
//   - `authedPage` fixture — a logged-in page, ready to drive
//   - `mockAI(page, overrides)` — installs page.route() handlers that
//     intercept AI endpoints and return canned JSON. Pass `{ real: true }`
//     or set E2E_USE_REAL_AI=1 to bypass mocking and call real backend.
// ============================================================
