## Overview

Classical International Typographic Style: flat whites, blacks, a disciplined grid, and a decisive red signal.

## Colors

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

- **Primary (`#000000`):** Headlines and core text.
- **Secondary (`#555555`):** Borders, captions, and metadata.
- **Tertiary (`#DC2626`):** The sole driver for interaction. Reserve it.
- **Neutral (`#F5F5F5`):** The page foundation.

## Typography

- **display:** Inter Tight 4rem
- **h1:** Inter Tight 2.25rem
- **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.
