// stubEmptyPartsManifest points the released-parts-manifest fetch at a local

// Gitea host. Use it in tests that build the non-optional `parts` consumer but
// do not depend on any released part rows.
//
// It is per-test (t.Setenv) on purpose: a package-global SOW_ASSETS_SERVER_URL
// would override the git-remote-derived server that other tests configure.
