## Overview

A scientific-journal palette: paper-white columns, plate-blue chart accent, strict rag-right.

## Colors

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

- **Primary (`#121213`):** Headlines and core text.
- **Secondary (`#606368`):** Borders, captions, and metadata.
- **Tertiary (`#1A4B8C`):** The sole driver for interaction. Reserve it.
- **Neutral (`#FAF9F5`):** The page foundation.

## Typography

- **display:** Source Serif 4 4rem
- **h1:** Source Serif 4 2.2rem
- **body:** Source Serif 4 1rem
- **label:** IBM Plex Sans 0.72rem

## 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.
