A robust theming system enables applications to support multiple visual appearances (light/dark modes, brand themes) while maintaining consistency and developer experience. Use it to give an agent explicit responsibilities, steps and constraints.

Design tokens are the atomic values of a design system - the smallest pieces that define visual style. They bridge the gap between design and development by providing a single source of truth for colors, typography, spacing, and other design decisions. Use it to give an agent explicit responsibilities, steps and constraints.
