## Overview

Built for dashboards. Cool grey scaffolding, cobalt action, strong type hierarchy, no decoration.

## Colors

The palette is built around high-contrast neutrals and a single accent that drives interaction.

- **Primary (`#111827`):** Headlines and core text.
- **Secondary (`#6B7280`):** Borders, captions, and metadata.
- **Tertiary (`#2563EB`):** The sole driver for interaction. Reserve it.
- **Neutral (`#F9FAFB`):** The page foundation.

## Typography

- **display:** Inter 3.5rem
- **h1:** Inter 2rem
- **body:** Inter 0.95rem
- **label:** Inter 0.75rem

## Do's and Don'ts

- **Do** use Tertiary for exactly one action per screen.
- **Do** let Neutral carry the composition — negative space is a feature.
- **Don't** introduce gradients. This system is flat on purpose.
- **Don't** mix Tertiary with alternate accents; the single-accent rule is load-bearing.
