+### Podział odpowiedzialności widoków

+Interaktywny diagram UML pokazuje przepływ i służy do wyboru kroku. Nie
+renderuje pod SVG osobnych paneli kodu, terminala, rejestrów, pamięci ani ramki
+stosu. Te dane prezentuje `Nvim view`, ustawiany przez snapshot wybranego
+kroku. Snapshoty pozostają w JSON/API, mimo że nie są powielane wizualnie pod
+diagramem.
