A toy-repair guide idea
Given: LOOK→A “Look at a drawing of a pretend loose wheel”; ASK→B “Ask a familiar grown-up about the drawing”; both pages have Back. No real repair steps, tools or safety instruction are supplied. Job / invitation: Choose a helpful page and return or finish. Worked: Back from ASK shows START without erasing either page. Finish ends the run. It does not fix an actual wheel or prove someone asked a question. Next: On paper keep the authored cards after Finish, showing navigation and deleting are different actions.
