A weekend book festival — a programme of events (as events, each a dated session): headline talks, panels, poetry readings, a debut showcase and a children's day, with a writers collection, a programme calendar, per-event seat booking and a membership form, over the app's own /api.
Open The Margins — Book Festival in the no-code builder and it reshapes itself as you chat — rename it, retheme it, add screens, change the data model. Publish when you are ready. You are not editing a page: the template is a complete product, with a web app, a native mobile app, a REST API and a seeded database.
