Content structure · hard
STR-03
Use parallel structure in lists and sequential steps. Each item should follow the same grammatical pattern. In multi-step flows, a final result-state item ('You're ready to go', 'Your account is set up') may shift to declarative when it describes an outcome rather than an action.
