## Users

React developers evaluating or using Luke UI to build accessible interfaces.

## Product Purpose

Luke UI is a React design system built with React Aria Components. Its documentation helps
developers understand the system, evaluate its behaviour, and use its components and themes through
accurate, runnable examples.

## Positioning

Luke UI combines accessible React Aria behaviour with statically generated styling and a themable
component system. Themes may intentionally have substantially different visual identities.

## Operating Context

Developers browse the documentation, inspect component examples and source code, and use the
playground to try examples before adopting them in an application.

## Capabilities and Constraints

- Luke UI is pre-1.0. Its public API is intentionally unstable while the design system is being
  shaped.
- Documentation examples must remain accurate and runnable.
- Components must remain accessible and usable across themes, even when their visual treatments
  differ substantially.

## Brand Commitments

The documentation and components do not have a fixed visual identity yet. Their visual design may
change, and themes can look substantially different from one another.

## Evidence on Hand

The repository contains the public component package, two bundled themes, hosted documentation,
runnable examples, a playground, and automated unit, browser, and visual checks. Do not claim
customer adoption without evidence.

## Product Principles

- Demonstrate behaviour with accurate, runnable examples.
- Treat accessibility and interaction quality as product behaviour.
- Let themes express genuinely different visual identities.
- Change immature pre-1.0 contracts when a better design requires it.
