error[KORU124]: transform 'router' invoked in continuation position is not supported here
  --> tests/regression/300_ADVANCED_FEATURES/350_SUBFLOWS/350_012_nested_router/input.kz:29:0
  this transform uses the whole-program escape, which matches flow-root invocations only; a continuation-position invocation is never rewritten (frontier: 210_024_source_scope_capture).
  fix: invoke 'router' at top level, or have it return a site-local SiteResult instead of a whole_program.

// REGRESSION TEST - Nested Router (Tree-Structured Routing)

//   | [GET /api/health] |> response { ... }
//   | [*] |> orisha:router(req)        <-- nested router
//       | [GET /other] |> response { ... }
//       | [*] |> response { ... }       <-- inner catch-all
