/**
 * Playwright configuration for browser extension E2E tests.
 *
 * These tests load the real extension and interact with it using Playwright.
 * The extension must be built first using `npm run build:chrome`.
 *
 * Test Organization:
 * - Tests are numbered (1.x, 2.x, etc.) and run in alphabetical order
 * - fullyParallel is disabled to ensure tests run sequentially
 * - Each test gets a fresh browser context via fixtures
