/**
 * Playwright covers two kinds of tests in this repo:
 *  1. `tests/e2e/build-output.spec.ts` — file-system assertions over `dist/`.
 *     These don't need a browser but ride along with the Playwright runner so
 *     they share CI job setup with the render specs.
 *  2. `tests/e2e/render.spec.ts` — real browser assertions against the Astro
 *     preview server.
 *
 * Both require a prior `NODE_CMS_USE_FIXTURE=1 npm run build`. We don't build
 * from Playwright because the build step is a prerequisite for dist-output
 * assertions — building inside `webServer` would race.
