/**
 * E2E config for the React WEB APP (web/standalone editor at :3048 + the
 * @pcbjam/backend-example reference backend at :3060), as opposed to
 * playwright-kicad.config.ts which drives the standalone tool harness HTMLs
 * under tests/apps/kicad.
 *
 * These tests exercise the real web open paths: navigate to /p/<project>/<tool>/<file>,
 * let WasmTool boot the tool in-document (boot.ts), drive the project into MEMFS
 * and auto-open the file (open-flow.ts via Module.kicadOpenFile), and assert the
 * editor loaded wizard-free.
 *
 * The backend serves a single project off the local filesystem — no DB, no
 * seeding. The webServer block reuses an already-running stack (`pnpm dev` from
 * web/) or cold-starts it with the env below, pointing PROJECT_DIR at the
 * committed tests/fixtures/demo project (slug "demo").
 *
 * Firefox is the reliable headless target on ARM Mac (Chromium SwiftShader WebGL
 * bug); use --project=chromium (system Chrome) for headed debugging.
