React Auth Email Tests: A TypeScript Pattern to Eliminate State Drift
A common pain point in React auth flows is state drift between UI state and actual email delivery, causing flaky tests.

This approach reduces guesswork and makes auth email tests more reliable by ensuring traceability from request to inbox.
