Verified steps

  1. Use locator-based waits (locator.waitFor / expect) — never sleep()
  2. Prefer stable selectors: roles, data-testid, text — not generated CSS classes
  3. Block images/fonts via route interception for speed
  4. Persist storageState for authenticated sessions; randomize timing modestly
  5. Respect robots.txt and site terms; throttle politely
