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.

Export pack

Start with DESIGN.md, then take only the extras you need

The main download is human-readable Markdown. JSON is available only as an optional design-token file.

# Developer changelog blog

## Product direction

- **Page type:** documentation
- **Layout archetype:** documentation
- **Audience:** Developers following product releases and engineering decisions
- **Goal:** Make product changes easy to discover, understand, and verify.
- **Tone:** Technical, transparent, and concise

## 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 compact; base radius is 6px; 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 | `#0d1117` | Page canvas and the deepest application layer |
| Surface | `#161b22` | Cards, panels, navigation, and raised regions |
| Text | `#f0f6fc` | Primary copy, labels, and high-emphasis content |
| Muted | `#8b949e` | Secondary copy, metadata, and inactive controls |
| Accent | `#58a6ff` | Primary actions, focus, selection, and active state |
| Success | `#3fb950` | Confirmed success and healthy state |
| Warning | `#d29922` | Caution, pending review, and non-blocking risk |
| Danger | `#f85149` | 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. Latest release
2. Breaking changes
3. Migration notes
4. Code examples
5. Archive
6. RSS

## 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.
