Prompt

I want to create a flexible, reusable custom trigger button component for our shared frontend library in React. Please write a TypeScript component that supports multiple visual variants and sizes using class-variance-authority, while supporting composition with custom underlying element types.

Repo notice (Asymmetric-al/core): This repository is Base UI only. Shared primitives come from @base-ui/react via the shadcn base-maia style in packages/ui. Ignore any Radix UI guidance below — never add radix-ui/@radix-ui/* imports or dependencies; composition uses Base UI's render prop, not asChild. See docs/ai/rules/frontend.md.

Design System Patterns

Master design system architecture to create consistent, maintainable, and scalable UI foundations across web and mobile applications.

When to Use This Skill

Creating design tokens for colors, typography, spacing, and shadows
Implementing light/dark theme switching with CSS custom properties
Building multi-brand theming systems
Architecting component libraries with consistent APIs
Establishing design-to-code workflows with Figma tokens
Creating semantic token hierarchies (primitive, semantic, component)
Setting up design system documentation and guidelines

Core Capabilities

1. Design Tokens

Primitive tokens (raw values: colors, sizes, fonts)
Semantic tokens (contextual meaning: text-primary, surface-elevated)
Component tokens (specific usage: button-bg, card-border)
Token naming conventions and organization
Multi-platform token generation (CSS, iOS, Android)

2. Theming Infrastructure

CSS custom properties architecture
Theme context providers in React
Dynamic theme switching
System preference detection (prefers-color-scheme)
Persistent theme storage
Reduced motion and high contrast modes

3. Component Architecture
