## Test Validation Loop

After writing or modifying tests:

1. **Run tests**: `npx playwright test --reporter=list`
2. **If tests fail**:
   - Review error output and trace (`npx playwright show-trace`)
   - Fix locators, waits, or assertions
   - Re-run tests
3. **Only proceed when all tests pass**
4. **Run multiple times** for critical tests: `npx playwright test --repeat-each=5`
