/**
 * Playwright config for the headless-render mount lane (tests/e2e).
 *
 * This lane does NOT spawn the server itself: `scripts/e2e-mount.sh` boots a
 * real `dsh web` instance (with the npm-packed plugin mounted through the
 * official `dsh plugin add` channel) and injects the base URL through
 * `DSH_E2E_URL`. The spec's job is to render that URL in a headless Chromium
 * and prove the plugin mounts without crashing the shell.
 *
 * Specs are named `*.e2e.ts` (not `*.spec.ts`) so vitest's default include
 * never collects them; vitest.config.ts excludes the directory as well.
