A martial arts dojo — programs (BJJ, Muay Thai, karate, kids), the belt journey, coaches as bookable resources, a trial booking, memberships and reviews, over the app's own /api.
Open Ironkata — Martial Arts Dojo 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.
