## Overview

A developer-first platform for building internal tools.

*The internal tooling equivalent of an enterprise-grade IDE.*

## Colors

High-contrast utility with warm, muted neutrals and cool blue accents.

- **Background (`#151515`)** — uses `bg` token
- **Primary text (`#E9EBDF`)** — uses `ink` token
- **Secondary text (`#CBCC C4`)** — uses `ink-soft` token
- **Accent (`#518DD2`)** — uses `accent` token
- **Muted (`#8B867F`)** — uses `muted` token
- **Borders (`rgba(233, 235, 223, 0.12)`)** — uses `line` token

## Typography

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

## Layout

Full-width dark background with a centered, constrained content area.

*Rhythm:* Consistent 4px base with 24px gutters and generous vertical padding for breathing room.

## Elevation & Depth

- 0px 1px 2px rgba(0, 0, 0, 0.12)
- 0px 68px 116px rgba(0, 0, 0, 0.35)
- Borders: 1px solid rgba(233, 235, 223, 0.12) for subtle separators; 1px solid rgb(233, 235, 223) for active states.

## Shapes

- `sm`: 4px
- `md`: 8px
- `lg`: 20px
- `pill`: 9999px

## Components

- **button:** Pill-shaped buttons with a solid white/light background for primary actions (Start for free) and transparent bordered backgrounds for secondary actions (Book a demo).
- **card:** Clean, slightly rounded containers with subtle borders or background differentiation to showcase product interfaces.
- **chip:** Small, rounded tags or labels with minimal padding, often containing monospaced text for technical concepts.
- **input:** Rounded input fields with clean borders and light backgrounds for search or command inputs.
- **hero:** A massive, centered headline pair followed by a floating product UI demonstration over a subtle gradient background.

## Do's and Don'ts

**Don't:**
- Don't use high-saturation neon colors — screenshot shows a palette of warm grays, dark backgrounds, and a single cool blue accent.
- Don't use decorative serif fonts for headlines — screenshot shows a clean, functional grotesque-sans for large display text.
- Don't use sharp 90-degree corners for main containers — screenshot shows a preference for soft, large-radius rounding (pill shapes or 20px+ curves).
- Don't use busy, textured backgrounds — screenshot shows smooth gradients and clean, solid dark surfaces.
- Don't use tiny, cramped layouts — screenshot shows generous spacing and large typography for a clear hierarchy.
- Don't use multiple competing accent colors — screenshot shows a restrained use of blue and warm orange/red only in specific graphic contexts.

## System Prompt (paste into AI agent)

```
A developer-focused SaaS platform for building internal tools. The design uses a dark mode palette with warm, muted grays (#151515, #E9EBDF) and a cool blue accent (#518DD2). Typography features a clean grotesque-sans for display and a humanist-sans for body text, with a heavy emphasis on large, thin-weight headlines. The layout is centered and spacious, with generous padding. Critical don'ts: never use high-saturation neon colors, avoid decorative serifs for headlines, and don't use sharp 90-degree corners for main UI containers. The tone is direct, technical, and confident.
