Use with AI Coding Agents

Copy one of these prompts into your AI coding agent to apply the Tailwind UI (component system reference) design system to your project. The DESIGN.md file in your repo root is the source of truth.

# .cursor/rules (or DESIGN.md)
You are working in a project that uses the Tailwind UI (component system reference) design system.

Read the DESIGN.md file in this project root and follow it strictly when generating UI.
Match the brand's exact colors, typography, spacing scale, and border radius.
Do not create generic Tailwind UI — apply the visual language from DESIGN.md.

Key rules:
- Use the defined color palette, not arbitrary hex values
- Apply the correct font family and weight scale
- Follow spacing tokens (4/8/12/16/24/32px scale)
- Match component patterns: buttons, cards, inputs, badges as specified
