Prisma Composer core concepts

A Prisma App is a tree of typed declarations composed in TypeScript and handed to the prisma-composer CLI. This file covers structures, hierarchies, relationships, and workflows: the concepts you cannot observe from the code or the CLI's help output. It is not a CLI reference; discover any individual command and its flags with --help. Commands named here belong to the prisma-composer CLI itself; a host CLI that embeds Composer may not carry every verb, so confirm a command exists via --help rather than inferring it. The Prisma platform moves fast, so treat this file as the stable conceptual core and find current, fuller documentation at https://www.prisma.io/docs. For working code, read examples/ in the prisma/composer repo.

Two principles govern everything and are binding (docs/design/01-principles/):
