/**
 * Playwright E2E configuration for LinkBreeze.
 *
 * Tests run against the live demo instance (Docker container on port 3010).
 * This avoids needing better-sqlite3 to work natively on the dev machine.
 *
 * The demo DB is read-only (DEMO_MODE), so tests verify read paths and
 * the public-facing UI. Write-path tests use the API with auth cookies.
 *
 * To run locally:
 *   npx playwright test
 *
 * In CI, set BASE_URL to point at a preview deployment.
