The cache key doesn’t include runner OS/arch, but the contents of ~/.cache/ms-playwright are OS-specific browser binaries. Including something like ${{ runner.os }} (and potentially ${{ runner.arch }}) in the key helps avoid restoring incompatible binaries if the job ever runs on a different runner image or OS.
