// This is where the extracted platform diagrams land. The shape below is
// illustrative only: it shows how a mocked dependency, a real service and a
// remote system are meant to sit together, not what the system actually is.
//
// The intended end state is that this file stops being hand-written and is
// generated from the running cluster, so the diagram becomes a report of what
// exists rather than a drawing of what was once intended.
