/**
 * Experimental Playwright+Electron companion boot harness (retired).
 *
 * This harness attempted to launch the Electron-based companion app via
 * Playwright's Electron driver, but it cannot run in this environment because
 * Electron embeds Node.js 16.17.1 while the installed Playwright version
 * requires Node.js 18 or higher.
 *
 * Companion behavior is instead covered by:
 * - Playwright-based automation E2Es and integrations against fixtures.
 * - Electron build/init/DI smoke tests.
 * - Domain and application unit/integration tests.
 *
 * This file is intentionally implementation-empty to avoid misleading
 * Playwright+Electron coverage while keeping the historical entrypoint
 * discoverable.
