This is a solid foundation for Playwright-based E2E testing that pushes you toward the page object model and away from brittle selectors. The selector priority is spot on: data-testid first, then roles and labels, never CSS classes or XPath. The auth state reuse pattern alone will save you minutes on every test run. What I appreciate here is the opinionated structure with clear boundaries: this is for full user workflows across the stack, not component tests or API contracts. The wait strategy section is practical, showing you exactly what to use instead of those shameful `waitForTimeout(3000)` calls we've all written. The examples are Python/React focused but the patterns translate to any stack running Playwright.
