With Show Overview (default), the plan-choosing page is split: the steps on the left and a sticky Overview card on the right summarising the customer's choices (plan, days per week, number of meals, start date, totals). With Hide Overview the steps take the full width and the summary card is not rendered (account members' selector, if you use that feature, still shows). Note that the Show Price per meal line inside the overview only appears when the overview itself is shown.
