// @vitest-environment jsdom
// The built-bundle boot smoke: the ONE assembled-jsdom test that loads the
// real `packages/client/*/lib/client.js` artifacts through AppWebEntry's
// ModuleLoader path (loadBundle) and proves the boot graph
// assembles — staged activation across the immediately tier and the inject
// layers, per-plugin CSS injection, and a rendered journey reaching chat
// content from the keyless FixtureApiClient transport.
//
// Component behavior remains owned by per-package suites (SlotTestRuntime
// benches over src). This smoke additionally pins the resident interaction
// fixture's cross-plugin projection because only the built connection/runtime/
// workspace graph can prove that transport-to-row path end to end.
