Data Storage

Requirements

When to Use

1. **Starting a new web project** — quickly reference standard color palettes, font pairings, and grid layouts without leaving the terminal

2. **Checking responsive design** — look up breakpoint values (sm/md/lg/xl/2xl) to ensure your CSS media queries follow common conventions

3. **Reviewing accessibility** — use the `contrast` command to get the WCAG contrast checker link and the `checklist` command for a quick design audit

4. **Prototyping UI components** — reference spacing scales and shadow presets to maintain consistent visual rhythm across your design

5. **Onboarding a new designer or developer** — share the tool as a quick-reference cheat sheet for design system fundamentals
