## Overview

Financial-grade trust with warmth. Deep navy primary, clean sans, violet-blue accent for interactive surfaces.

## Colors

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

- **Primary (`#0A2540`):** Headlines and core text.
- **Secondary (`#425466`):** Borders, captions, and metadata.
- **Tertiary (`#635BFF`):** The sole driver for interaction. Reserve it.
- **Neutral (`#F6F9FC`):** The page foundation.

## Typography

- **display:** Sohne 4rem
- **h1:** Inter 2.25rem
- **body:** Inter 1rem
- **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.
