/**
 * Page Object Pattern
 *
 * Extend BasePage to add page-specific selectors and actions.
 * Each route gets its own file: pages/LoginPage.ts, pages/DashboardPage.ts
 *
 * Example LoginPage (create at tests/playwright/pages/LoginPage.ts):
 *
 *   import { BasePage } from './BasePage';
 *   import type { Page } from '@playwright/test';
 *
 *   export class LoginPage extends BasePage {
 *     get usernameInput() { return this.byLabel('用户名'); }
 *     get passwordInput() { return this.byLabel('密码'); }
 *     get submitBtn() { return this.byRole('button', { name: '登录' }); }
 *
 *     constructor(page: Page) { super(page); }
 *
 *     async login(user: string, pass: string) {
 *       await this.goto('/login');
 *       await this.fillAndVerify(this.usernameInput, user);
 *       await this.fillAndVerify(this.passwordInput, pass);
 *       await this.click(this.submitBtn);
 *     }
 *   }
 *
 * Usage in spec:
 *   import { LoginPage } from '../pages/LoginPage';
 *   const loginPage = new LoginPage(page);
 *   await loginPage.login('user@example.com', 'password');
