The parent held one @switch with three @case blocks — three screens'
markup in one file. Each case is independent and needs only the
answers, the errors, and (for two of them) the scholing threshold.
Extract buitenland.step.ts, werk.step.ts, and review.step.ts as pure,
presentational steps: inputs down, one narrow output up, dispatch
never passed down. The parent keeps the store, the shell, and
draftSync, and maps each step's output back to a machine message.
This is the first *.step.ts in the repo, so it sets the naming
convention that RD-23 does the same job with.
