## Overview

A dark, precision-focused SaaS design system for developer tools.

*A high-end watch instrument for software teams—dark, precise, zero decoration.*

## Colors

Extreme contrast for focus, with subtle noise and semi-transparent layers to create depth.

- **Background (`#08090A`)** — uses `bg` token
- **Primary text (`#F7F8F8`)** — uses `ink` token
- **Secondary text (`#D0D6E0`)** — uses `ink-soft` token
- **Muted (`#62666D`)** — uses `muted` token
- **Borders (`rgba(255,255,255,0.08)`)** — uses `line` token

## Typography

- **Display:** geometric-sans
- **Body:** humanist-sans
- **Mono:** monospace

- Use tight negative tracking on large headlines.
- Maintain 400 weight for body text to keep the interface light.
- Use mono fonts exclusively for technical references and identifiers.

## Layout

Dense, full-width dark canvas with nested elevated panels.

*Rhythm:* Strict 4px grid with tight component spacing.

## Elevation & Depth

- 0px 1.2px 0px 0px rgba(0,0,0,0.03)
- 0px 2px 4px 0px rgba(0,0,0,0.4)
- inset 0px 0px 12px 0px rgba(0,0,0,0.2)
- Borders: 1px solid rgba(255,255,255,0.08)

## Shapes

- `sm`: 4px
- `md`: 6px
- `lg`: 12px
- `pill`: 9999px

## Components

- **button:** Pill-shaped or slightly rounded rectangles with transparent backgrounds and thin borders.
- **card:** Elevated dark panels with a subtle 1px inner border and soft drop shadows.
- **chip:** Small, rounded rectangles used for tags and status indicators.
- **input:** Dark, semi-transparent background fields with minimal border styling.
- **hero:** Massive, bold sans-serif headline paired with a clean subheader and a large product mockup.

## Do's and Don'ts

**Don't:**
- Don't use high-saturation colors — screenshot shows a strictly grayscale/white palette.
- Don't use rounded, playful shapes — screenshot shows sharp or very subtly rounded corners.
- Don't use serif or decorative fonts — screenshot shows a clean, geometric sans-serif.
- Don't use bright, colorful gradients — screenshot shows a dark, flat, grain-textured background.
- Don't use thick, heavy borders — screenshot shows hairline 1px dividers.
- Don't use complex, multi-layered shadows — screenshot shows only subtle, low-opacity drop shadows.

## System Prompt (paste into AI agent)

```
Design a high-precision SaaS interface for developer tools and AI-era productivity. The system uses a deep dark mode palette, primarily #08090A for backgrounds with white #F7F8F8 text for high contrast. Typography is clean and geometric, with negative tracking for large headlines. Key hex colors are #08090A, #F7F8F8, and #62666D for muted elements. Do not use high-saturation colors or playful, rounded shapes; the aesthetic must remain sharp, technical, and professional. The layout is dense and full-width, utilizing semi-transparent panels to create depth. Ensure transitions are fast and subtle to maintain a sense of velocity.
