# Design System

## Overview
A focused, minimal dark interface for a developer productivity tool.
Clean lines, low visual noise, high information density.

## Colors
- **Primary** (#2665fd): CTAs, active states, key interactive elements
- **Secondary** (#475569): Supporting UI, chips, secondary actions
- **Surface** (#0b1326): Page backgrounds
- **On-surface** (#dae2fd): Primary text on dark backgrounds
- **Error** (#ffb4ab): Validation errors, destructive actions

## Typography
- **Headlines**: Inter, semi-bold
- **Body**: Inter, regular, 14-16px
- **Labels**: Inter, medium, 12px, uppercase for section headers

## Components
- **Buttons**: Rounded (8px), primary uses brand blue fill
- **Inputs**: 1px border, subtle surface-variant background
- **Cards**: No elevation, relies on border and background contrast

## Do's and Don'ts
- Do use the primary color sparingly, only for the most important action
- Don't mix rounded and sharp corners in the same view
- Do maintain 4:1 contrast ratio for all text

## Overview
A minimal dark interface for a developer productivity tool.
Clean lines, low visual noise, high information density.

## Colors
- Primary (#2665fd): CTAs and active states
- Surface (#0b1326): Page backgrounds
- On-surface (#dae2fd): Text on dark backgrounds

## Typography
- Headlines: Inter, semibold
- Body: Inter, regular, 14-16px
- Labels: Inter, medium, 12px, uppercase

## Layout
- 8px base spacing unit, scale: 4 / 8 / 16 / 24 / 32 / 48
- Max content width 720px with 24px gutters on mobile

## Elevation & Depth
- Surfaces rely on background contrast instead of shadow
- Overlays use an 8 percent white tint on dark surfaces

## Shapes
- Rounded 8px for controls, 16px for cards
- Avoid mixing sharp and rounded corners in one view

## Components
- Buttons: 8px rounded, primary filled with brand blue
- Inputs: 1px border, subtle surface-variant background
- Cards: no elevation, rely on border and background contrast

## Do's and Don'ts
- Do use the primary color sparingly, for the most important action
- Don't mix rounded and sharp corners in one view
- Do maintain at least a 4:1 contrast ratio for all text

spacing and component tokens instead of inventing new values.
