// The built-bundle boot smoke: the assembled-jsdom test that owns the boot
// graph itself. Other files share the same scaffolding (assembled-boot.ts) to
// reach a surface only the built bundles expose; this one asserts that the
// graph assembles at all — staged activation across the immediately tier and
// the inject layers, per-plugin CSS injection, and a rendered journey reaching
// chat content from the keyless fixture Connection RPC.
//
// 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,
// Controller, UI adapter, and Workspace graph can prove that transport-to-row
// path end to end.
