A weekend science festival on the events + cms + forms stack — six live events (planetarium show, chemistry demo, family robotics, hands-on animals, physics of music, and a live panel) each a dated show with capacity and seat booking, a presenters collection, a weekend sessions calendar, ticket tiers, and a newsletter/groups form, over the app's own /api.
Open SPARK — Science 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.
