Generate a Playwright Page Object (POM) class for the TTACart demo app (app.thetestingacademy.com/playwright/ttacart) by driving the live page and reading its real selectors. Use this whenever the user gives a TTACart page URL plus a flow to reach it and asks to "create a page object", "build the POM", "scaffold a page class", "POM this page", "generate the page object for the checkout/inventory/cart page", or pastes a TTACart URL and wants a typed page class — even if they don't say the word "POM". The generated class extends BasePage and matches the existing LoginPage / CartPage / InventoryPage conventions exactly (data-test locators, .js ESM imports, the `el` wrapper, `open()` + `assertLoaded()`), then is wired into the pages barrel and verified with typecheck + lint.
