An app is a running demo: a small web interface in front of a model, a dataset or your own code.
Shown on the app and on the model it uses.
Anyone can see it. Only you can push to it.
No database is connected in this environment, so what you create is held in this browser. ARCHITECTURE.md and prisma/schema.prisma describe where it would be written, and which object store the files would land in.
