The apps overview maps the platform's plugins/ workspace. Built-in plugins demonstrate the shared shell, while Tasks, Shopper, Plainwrite, and Wallet show first-party domain apps at different levels of scope and maturity. The example-* plugins are narrower SDK and shell references.
Use app in user-facing copy and plugin for manifests, APIs, database schemas, packages, and developer documentation.
