## Overview

A calming wellness palette without the spa cliches. Muted matcha green, warm oat, quiet ink.

## Colors

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

- **Primary (`#2B3A2E`):** Headlines and core text.
- **Secondary (`#7A8A72`):** Borders, captions, and metadata.
- **Tertiary (`#6F9A5B`):** The sole driver for interaction. Reserve it.
- **Neutral (`#ECE8DB`):** The page foundation.

## Typography

- **display:** Noto Serif 4rem
- **h1:** Noto Serif 2.5rem
- **body:** Noto Sans 1rem
- **label:** Noto Sans 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.
