Automated E2E Testing with Playwright & Page Object Model (POM)

Automate headless browser interactions using Playwright, encapsulate UI selectors with Page Object Model classes, and handle dynamic web states.

Page Object Model (POM) Design Pattern

### Why Use Page Object Model? Hardcoding CSS selectors (`#submit-btn-login`) directly inside test files causes fragile tests when UI design changes. **Page Object Model** encapsulates page layout selectors and actions into dedicated class objects.
