## Overview

A split-flap departure-board palette: flap-black panel, amber status chars, disciplined mono.

## Colors

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

- **Primary (`#F2B53A`):** Headlines and core text.
- **Secondary (`#8E6F25`):** Borders, captions, and metadata.
- **Tertiary (`#F2F2EF`):** The sole driver for interaction. Reserve it.
- **Neutral (`#0D0D0D`):** The page foundation.

## Typography

- **display:** IBM Plex Mono 3rem
- **h1:** IBM Plex Mono 1.7rem
- **body:** IBM Plex Mono 0.92rem
- **label:** IBM Plex Mono 0.7rem

## 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.
