How to use it

The preset is useful without AI and does not execute code.

01
Preview and customize
Check desktop and mobile, then open the visual builder if the palette, typography, spacing, or sections need adjustment.
02
Download DESIGN.md
Save it in the repository root. It contains readable design rules plus the versioned machine-readable DesignBrief.
03
Connect your agent
Add the generated integration snippet to AGENTS.md, CLAUDE.md, or GEMINI.md so the agent explicitly reads the design system.

DESIGN.md is a OneLiners convention. The included integration file explains exactly how to use it with your selected agent.

# SaaS control panel

## Product direction

- **Page type:** application
- **Layout archetype:** application
- **Audience:** Business and technical SaaS users
- **Goal:** Make frequent configuration tasks predictable and reversible.
- **Tone:** Clear, supportive, and efficient

## Visual system

- Use the semantic palette below; never use color without meaning.
- Heading: Inter, ui-sans-serif, system-ui, sans-serif; body: Inter, ui-sans-serif, system-ui, sans-serif; code: JetBrains Mono, ui-monospace, monospace.
- Density is comfortable; base radius is 8px; shadows are subtle.
- Icons: Lucide-style outline icons with consistent 1.75px strokes.
- Imagery: Use product-specific imagery only when it explains the workflow; never use decorative filler..

## Semantic palette

| Role | Value | Intended use |
| --- | --- | --- |
| Background | `#f5f7fb` | Page canvas and the deepest application layer |
| Surface | `#ffffff` | Cards, panels, navigation, and raised regions |
| Text | `#172033` | Primary copy, labels, and high-emphasis content |
| Muted | `#667085` | Secondary copy, metadata, and inactive controls |
| Accent | `#2563eb` | Primary actions, focus, selection, and active state |
| Success | `#16803c` | Confirmed success and healthy state |
| Warning | `#a15c00` | Caution, pending review, and non-blocking risk |
| Danger | `#c52b2b` | Errors, destructive actions, and blocking risk |

The optional `design-tokens.css` from the full export pack mirrors these values. This `DESIGN.md` remains complete when used on its own.

## Layout and content

1. Application header
2. Workspace navigation
3. Summary
4. Configuration form
5. Activity
6. Confirmation

## Responsive and accessibility

- Collapse sidebars into an explicit drawer and preserve the primary task before secondary metadata..
- Meet WCAG AA contrast, preserve visible focus, and respect reduced motion.
- Do not reduce essential content or actions on mobile.
