What is a Module?
A Module is a versioned composition of Library components plus its own state, APIs, functions, outputs, public commands, lifecycle rules, CSS, and preview scenarios. Schema version 2 is the current canonical workspace contract.
Inputs and outputs
Declare a stable public interface instead of leaking internal state to the Application.
Functions and APIs
Build explicit steps for state changes, API calls, conditions, transforms, and emitted outputs.
Responsive behavior
Set viewport-aware classes and visibility rules, then verify them in preview.
Good boundary: a Module should solve one reusable product responsibility, such as a search panel, checkout summary, or account header—not an entire application.
