- * suites, which the sandbox build never runs, and Playwright's install script -- the one

- * all lifecycle scripts. `--no-devel` is not the answer: the generator does not support
- * it for pnpm lockfile v9, and the build needs the other devDependencies anyway (Vite,
- * esbuild and tsx are the build toolchain).

- * The generator is installed from its master branch, so the checks guard against its
- * output drifting: a filter that no longer matches would quietly reship the archives,
- * and a collapsed count or missing Electron zip would only fail the flatpak build much
- * later, inside the sandbox.
