Shadow DOM
Elements inside Shadow DOM boundaries. Regular CSS/XPath selectors can't cross shadow roots — learn how each tool handles it.
About Shadow DOM: Elements inside a shadow root are encapsulated.
Playwright uses
page.locator('custom-el').locator('inner') or
>>> combinators. Selenium 4+ uses getShadowRoot().
Cypress uses cy.get('host').shadow().find('inner').
